    When reading any essay about the perils & merits of Bluesky's architecture, save yourself some time by searching for "Blacksky" in the post. If they don't address Blacksky, more than likely the author's understanding of the space has major gaps.

    (Blacksky is the/one of the furthest along in building competing versions of each part of the AT proto stack.)

      I know very well what it is, it doesn’t change anything in the grand scheme of things. I wish it did!

      • runako 11 hours ago ago

        Re-reading my reply, it is worded more harshly than I intended. My apologies.

        I do think it's a critical omission to not address the main player(s?) who are working on key parts of this, and where they may yet run into problems.

    • api 12 hours ago ago

      Does it require people change defaults? If so then 99% will never use it.

      A system or protocol is whatever the easiest user journey is. Anything outside of that will never be seen by many users unless there is some value to be gained by going there. And that value has to be something gained now, not a hypothetical like insurance against future closing of the network. People don’t like to buy insurance.

    I might be misunderstanding something about atproto, but isn't it always possible to export data from bluesky because all it takes is reading your data, which is done by any app interacting with your pds anyway? If they block that, they're blocking atproto functionality entirely, no?

    • 8organicbits 12 hours ago ago

      > If they block that, they're blocking atproto functionality entirely, no?

      Keep in mind, twitter got rid of their API. Google got rid of XMPP federation. Bluesky breaking or defederating atproto wouldn't impact most users, so they'd probably get less outcry than those examples.

    Bluesky is architected so you can export your data and follows and followers to your own or someone else's infrastructure at any time. There are some groups that have taken that offer and moved off of Bluesky's infrastructure (see Blacksky). The fact that most people aren't doing that is a sign that people are happy with how Bluesky-the-company is running things. What's the issue?

    • kevinak 12 hours ago ago

      Most people were happy with Twitter as well

      • AgentME 12 hours ago ago

        And Bluesky is better because you're not locked in and can export your posts, follows, and followers off of their infrastructure if they start being evil or you randomly feel like it. Companies like Twitter effectively wield network effects to stop people from leaving. All of one's activity on Twitter increases the sunk cost to keep them on Twitter in a way that's not true for Bluesky.

        • fc417fc802 7 hours ago ago

          I recognize that Bluesky is at present more open than Twitter and that all of the necessary building blocks for the infra are publicly available. That's good of course.

          However I think the view you expressed there is misguided. If Bluesky locked out third party infra tomorrow presumably the vast majority of people would not move. Thus vendor lockin via network effects remains. (Ie you are always free to leave but you'd be moving from a metropolis to a backwater.)

          The only scenario where this isn't true is one where no more than a few percent of the people you interact with reside on any given node. By that metric small AP nodes pass while large ones such as the flagship Mastodon node fail. Similarly Gmail and Outlook fail while any self hosted mail server passes.

          It's not an easy problem to solve.

          I don't have a horse in this race, but:

          > [..] machine-readable archive of information associated with your account in HTML and JSON files. [..] including your profile information, your posts, your Direct Messages, your Moments, your media ([..]), a list of your followers, a list of accounts that you are following, your address book, Lists that you’ve created, are a member of or follow, [..], and more.

          (Note that I actually elided some additional things that are included in the export, for readability's sake.)

          • AgentME 11 hours ago ago

            You can't actually use your followers and following list from X on other sites. With Bluesky, you can move your profile onto other infrastructure, continue to see posts from people you follow, and make new posts that your followers still see like nothing happened. It's like how if you own your own domain name, you can set your MX records to whatever email service you want and change it when you want without affecting anyone you're having email conversations with.

            • mh- 11 hours ago ago

              Ah, I see. Your use of the term "export" made me misunderstand. Though now that I've thought about it for a few minutes, I'm not sure what verb makes sense [to me] there. I guess "migrate?"

              edit: also, thanks for clarifying!

      • esseph 9 hours ago ago

        That's a very strong statement to make.

    • zem 11 hours ago ago

      whether you agree or not, asking "what's the issue" misses the point very badly, since the article is almost entirely about what the issue is (i.e. that most people will not change defaults and the default is to centralise on the bluesky servers)

      • AgentME 11 hours ago ago

        The fact that the system is built around this escape hatch makes it miles better than almost all other social networks. An escape hatch doesn't need to be used by most people to be valuable.

        • kevinak 6 hours ago ago

          Nostr doesn’t have these issues

      • AlienRobot 11 hours ago ago

        It's weird to focus on that when there isn't a single thing in software that doesn't suffer from "everyone will just use the default anyway"

        • kevinak 6 hours ago ago

          Nostr doesn’t have these issues

        • zem 11 hours ago ago

          yeah I'm not saying the blog is right or wrong; I'm just saying that describing bsky's features and asking "what's the issue?" means you aren't engaging with what it's actually saying.

          • jmull 10 hours ago ago

            I’m not the previous poster, but I don’t see any cogent points in the article to engage with in any depth.

  • vvpan 12 hours ago ago

    > At every layer, the answer is "anyone can run their own." At every layer, almost nobody does.

    But people do and it is reportedly fairly easy so the majority of people are on Bluesky's layers while all is well. But also I don't understand why any of this is a reason to be "wary", it's a great place to be with some unique technical properties - it is way more "open" than any other platform of similar scale.

    • bo1024 10 hours ago ago

      > But people do and it is reportedly fairly easy so the majority of people are on Bluesky's layers while all is well.

      The post discusses why, when all is not well, it will be too late.

  • icehawk 12 hours ago ago

    > That's the same argument people made about Twitter. "If it goes bad, we'll just leave." We know how that played out.

    Yeah, it played out with my whole social circle leaving, as evidenced by the fact that all my friends link me to the bluesky post whenever there's something happening now.

  • shablulman 12 hours ago ago

    It’s easy to get caught up in the excitement of a fresh social graph, especially when the migration feels so organic. However, the author makes a poignant point about the inherent tension in building a protocol while simultaneously acting as its primary, VC-backed gatekeeper.

    The real test for the AT Protocol will be whether it can truly decouple from Bluesky PBC before the pressures of monetization or an exit strategy kick in. Right now, we’re benefiting from the "honeymoon phase" of a platform that needs growth more than revenue, but history suggests that the bridge to true decentralization needs to be fully built before that dynamic inevitably shifts.

    >> You can self-host a PDS. Almost nobody does.

    Who would've thought true decentralization means everyone hosting their own server? Yes, each user would have to pay and maintain it, but that's the cost of decentralization. ATProto at least makes it easy to jump ship if shit hits the fan and not have to start from scratch. Try doing that with Twitter/Instagram/Etc.

  • 8cvor6j844qw_d6 11 hours ago ago

    Bluesky's behavior here isn't surprising.

    They already ban signups using email aliases, and apparently block alias emails to their unban support address too.

  • JKCalhoun 12 hours ago ago

    "That's the same argument people made about Twitter. 'If it goes bad, we'll just leave.' We know how that played out."

    Yeah, I left.

    (And in fact I am wary of all social media.)

    • eviks 8 hours ago ago

      So it played very poorly, you lost personal data and most importantly, social connections, and acquired a weariness

  • Retr0id 12 hours ago ago

    There doesn't seem to be a timestamp associated with this article, but it is based on outdated information.

    • kevinak 12 hours ago ago

      How so?

      I should add a time stamp to the blog.

  • wmf 12 hours ago ago

    There are specific steps Bluesky could take to decentralize the network. These are going to sound extreme but I agree with the article that it will never decentralize on its own. (Nothing will ever decentralize on its own so this isn't a criticism of Bluesky specifically.)

    1. Strongly encourage backups.

    2. Force users to migrate off the "official" PDS until it has less than, say, 40% market share.

    3. Make the mobile apps use third-party relay/appview by default (could be randomized).

    • chickensong 8 hours ago ago

      > Strongly encourage backups

      Or invert this, and make it local-first. It's your data, and publishing it to a network is a form of backup. Either that, or the client holds a local copy by default.

      • wmf 8 hours ago ago

        It's not clear to me what a local-first social network would mean. The point is for other people to see your posts.

        • chickensong 8 hours ago ago

          The data is local-first, but it's designed so that you publish to online networks. The point is to invert the current model of putting your content into someone else's network and hoping for the best, or expecting users to remember to run some manual backup that's probably going to be a pain to do anything with.

  • browningstreet 12 hours ago ago

    Bluesky isn't my bank records, isn't my photo archive, isn't my github, isn't my Documents folder.

    I don't care if Bluesky goes away, gets bought, whatever.

    Social media is disposable like a retail outlet. I'm sad if the coffee shop around the corner goes out of business, but there are 99K coffee shops in the US. I can go to another one.

    As it is, I don't use Meta or X.. because they're led by despicable beings. Bluesky gets a pass for now, and has enough interesting people that I show up and have a chat. Like a coffee shop or a bar.

    • davidw 11 hours ago ago

      This is where I'm at, but it would be nice if it had some more longevity to it, as there are costs to switching to the next thing and the thing after that.

    • 627467 9 hours ago ago

      I dont get why you're downvoted.

      Social media should be treated as disposable. Anything that is not yours (as in, is hosted by someone else - for free) should be disposable. In fact id even argue that any media should be treated as disposable. You wouldn't hoard all the material things your accumulate in life, why would you hoard random tweets, comments and reactions forever?

      If its worth it, surely you'll find a way to keep it in a way that doesnt demand a third party to do it for you for eternity, no?

      "Switching costs" man... people move between countries with vastly different languages and cultures and they adapt, make new relationships, refresh ideas. Is switching from database A to database B that difficult really?

  • jeswin 10 hours ago ago

    True p2p is the only approach that will work, not federation. I'd go futher and make the protocol high-friction for federation.

    It's true that many p2p attempts have failed, but it's also the only solution that doesn't require someone running servers for free. There's evidence of success as well: napster (and bittorrent). Both were wildly successful, and ultimately died because of legal issues. It might work when the data is yours to share.

    • throwaway0665 10 hours ago ago

      I can't imagine a world where a p2p social network is practical. Not when each node is an unreliable mobile phone that's maybe on cellular. Even with something like ipfs you have pinning services, bittorrent has seed boxes, because pure p2p is impractical.

      • jeswin 9 hours ago ago

        You can have your other devices and friends replicating.

        • wmf 8 hours ago ago

          That uses a lot of bandwidth and battery. I'd rather find a better way to pay for servers than try to avoid them.

  • mcint 12 hours ago ago

    It's good FUD. You re-iterate their talking points. (Also, no CTA, no takeaway, just "worry!")

    As others have said, the data has to be publishable to be useful. We do have data export laws. The format is known to be ready to use interoperably, not some private schema--atop the PBC commitment, which will at least have moderate legal costs if not a guarantee. It has unequivocally set a new high bar.

    They seem pretty locked in to doing what they committed to. The day may come when they turn. It may come first by friction, but the turn has to be pretty complete, because the data is pretty open. What's needed to view it, use it at all, is pretty close to what's needed to host it.

    "The site whose value prop is sharing your posts and data with other apps may stop sharing your posts and data with other apps." Yeah, it's possible. It's also possible they just close.

  • davidw 13 hours ago ago

    Good points, but what's the alternative at this point?

    Because of network effects, more users is generally more interesting. Blue Sky has "enough" at this point for me to be happy there. Programmers like antirez, my bike racing people like inrng, my city's mayor and one of our city councilors, and also a bunch of urbanists.

    Edit: you lose some connections moving around, but I've also had friends I've known since the days of IRC. I think I'm mostly resigned to picking whatever works best in the moment and being willing to move (like abandoning Twitter) when it's not working.

      which is not opposed to you being on Bluesky or Instagram or LinkedIn or wherever.

      • seandoe 12 hours ago ago

        That's just not practical for most people (the publishing part). And in relation to microblogging, are you going to publish every 140-character, out-of-context thought on your personal website?

        • 8organicbits 12 hours ago ago

          There's other syndication models, although POSSE gets talked about most.

          If you don't want to get your own domain and run a server (not practical for most people) you can still protect yourself from being stuck in a single silo by broadcasting to many social media sites.

          https://indieweb.org/PESETAS

          • seandoe 12 hours ago ago

            And the atproto is pesetas right? You publish to bluesky or whatever and the content is replicated to your pds. I recognize the minor difference, but if you have the energy and wherewithal to orchestrate pesetas across silos, surely you can setup a pds elsewhere.

            • 8organicbits 12 hours ago ago

              I think of PESETAS as more defensive than what a single protocol can handle. Imagine posting to Bluesky and using automation to syndicate the post to Twitter, Facebook, Mastodon, Threads, and more. If Bluesky goes evil, or you otherwise decide to ditch it, you've mitigated the network effect as you have followers on other platforms already. People can still find you and your content isn't lost.

              Imagine if Bluesky decides to ban you, and continues to ban accounts you create elsewhere. Atproto ensures non-Bluesky PDS can see you, but you've lost 99% of the userbase.

              • seandoe 7 hours ago ago

                Ok yea that makes sense.

    • kevinak 12 hours ago ago

      Nostr - it has none of the problems mentioned in the article.

      • davidw 12 hours ago ago

        But does it have a critical mass of people?

        The Wikipedia page says "Nostr is primarily popular with cryptocurrency users, primarily Bitcoin users."

        That's not my crowd.

        • irusensei 12 hours ago ago

          I hear you but if you think about it who else has an incentive and skills to create something like Nostr? Who are the people interested in free speech, signatures and decentralization and with the skills to pull it up?

          And since you mentioned primarily Bitcoin users those are the crypto folks that seem to be very against the idea of tokenizing everything.

          From what I understand by posting something on Nostr you are posting signed events to a list of dumb relays. These events can be of many types and include hints of discoverability. There is no blockchain and no token and the thing they call zap is just a link to a lightning address that is up to the client to show.

          Your account is your key pair so you are not at the whims of a power tripping administrator.

          It seems like the perfect nesting ground for non corporate user content and pocket islands of communities. Nothing prevents someone from implementing a relay or community that bans any talk about Bitcoin or crypto. I for one would love to see closed content focused relays in Nostr.

    • manuelabeledo 12 hours ago ago

      Isn't Mastodon an alternative?

      • davidw 12 hours ago ago

        • loeg 12 hours ago ago

          If you're concerned about critical mass, Bluesky is also a dead end.

          • davidw 11 hours ago ago

            I mean, I explained in my original comment exactly why it is not a dead end for me. It has 'enough' of the things I'm interested in to make it worthwhile.

  • publius_frog 12 hours ago ago

    (Throwaway account.)

    Several people have mentioned that "you can just own your own data, so that's enough, right?"

    Interoperating with Bluesky requires you to either 1) opt into the did:plc standard, which is a centrally controlled certificate transparency log, or 2) have all your users create did:web accounts by manually setting DNS records.

    So it is not possible to build on Bluesky at all without opting into this centrally controlled layer. This original post covers this, but maybe not in enough detail to stop commenters from missing the point.

    Bluesky the company controls 95%+ of PDSes in the system, which control users' private keys, and they're extending PDSes to include more functionality that prevents users from easily exiting the network, e.g. private data is being implemented in a way where Bluesky LLC can see all your activity. The protocol changes often and with limited community input.

    This is being done because "there are no other ways to do it" and "our users are okay with it". The community does pretty consistently attack people who dissent (e.g. look at what happened when Mastodon leaders objected). There's a lot of cheerleading for people who do opt into the system, and there's really no incentive for informed criticisms.

    It's not really decentralized or neutral infrastructure; it's a great network for a number of specific subcultures who have a nice space away from X, and I hope the team embraces that.

  • qwertox 12 hours ago ago

    > If an acquirer disables exports, it doesn't matter that the tools existed yesterday.

    Don't they have to give you your data upon request? And the cheapest way is to offer an export function? Wasn't this thanks to the EU (GDPR Article 20)?

    • asadotzler 10 hours ago ago

      They can give it to you in the least useful way imaginable and will. What we want and expect is an export that can be easily imported to some other provider and that's where the "good guys" can differentiate.

      I can export decades of web browsing history, bookmarks, logins, etc. and import into any other browser with almost no trouble at all. Try to export your mainstream social network (facebook, twitter, insta, tiktok, etc.) content and connections and import it into another social network and let me know how that goes.

    • Spivak 12 hours ago ago

      Also, at best this says not to host your data on someone else's computer and keep control of it, which is a thing Bluesky explicitly supports and encourages.

      Will normal people do it, no. But you can.

  • themafia 10 hours ago ago

    I've never looked at the AT Protocol before. It seems like you could have achieved most of that with existing DNS, HTTP and RSS implementations. All they really needed was some file formats and some well known URL schems and all of this could have been far easier to implement and deploy.

          Why?

          • tptacek 11 hours ago ago

            It's good at spotting stuff, like:

            * Overusing verbs

            * Poor structure

            * Bad transitions between grafs

            * Passive voice

            And even bigger-picture stuff, like "you might want to zoom in here" or "this section isn't paying off". I've only in the past few months started using it for proofreading, and it's pretty solid.

            But if you take any of its words, you're infecting your writing with Claude's tone, and it will show.

            It's super useful as a reader of your writing. It's a terrible collaborator, unless you're writing for an audience of middle managers.

              • antonvs 10 hours ago ago

                Vocabulary is only part of it. LLM style is pretty recognizable, and most people don’t normally write like that. One reason is because they’re trained in a lot of marketing material, news articles, and the like. If it sounds like a self-unaware middle manager writing on LinkedIn, but it isn’t one, it’s probably an LLM.

    • kevinak 4 hours ago ago

      I do advocate for using other networks (specifically Nostr) that are not designed like this, but the network effect is big and most of my friends are on Blue Sky because they have been lured into a false sense of “it’s decentralised, I can just move! If something bad happens”.
