The framing of "portability" is a bit confusing. Your data is not actually "transferring" anywhere, it's always in your PDS. These other apps and clients are just frontends that are displaying the data that is in your PDS. The data is public and open, though private data is in the works and hopefully will arrive in 2026.

The data is not transferring, but the user is. When I sign up for e.g. Twitter, I don't want to sign up for Mastodon, or Bluesky, or Truth Social, or whatever other platform someone might create later. Thus I would not choose to put my data in a PDS. I feel like that would actually leave me with less ownership and control than I have now.

My point is that I don't believe the separation of frontend and data is desirable for a social network. I want to know that I am on a specific platform that gives me some degree of control and guarantee (to the extent that I trust that platform) over how my data is represented. I don't really have to worry that it's showing up in any number of other places that I didn't sign up for (technically I do since everything public can be scraped of course, but in practice there are safeguards that go out the window when you explicitly create something like a PDS).

Do I understand correctly that your main concern is that some random service would serve a page when asked for /your-handle, and so, given a link, someone may assume that you actively use that service? Just trying to understand the exact scenario.

Generally it's good practice for AT apps to treat you as not signed up if you have not explicitly signed up to this app before. So I think a well-behaved site you never used shouldn't show your profile page on request. If this is right, maybe it needs to be more emphasized in docs, templates, etc. Same as they should correctly handle lifecycle events like account getting deactivated.

Realistically it's possible some services don't do this well but it's not clear to me that this is going to be a major problem. Like if it gets really bad, it seems like either this will get fixed or people will adjust expectations about how profile pages work.

This sounds like I need to host my PDS. Easy for me with no public profile but if I was someone famous wouldn't that mean I needed enterprise class hosting?

[danabramov]

You don't need to host your own PDS for any of this to work. It works the same way regardless of who hosts your PDS.

I think what may be confusing you is that Bluesky (the company) acts in two different roles. There's hosting (PDS) and there's an app (bsky.app). You can think of these conceptually as two different services or companies.

Yes, when you sign up on Bluesky, you do get "Bluesky hosting" (PDS). But hosting doesn't know anything about apps. It's more like a Git repo under the hood.

Different apps (Bluesky app is one of them) can then aggregate data from your hosting (wherever it is) and show different projections of it.

Finally, no, if you're famous, you don't need enterprise hosting. Hosting a PDS can be extremely cheap (like $1/mo maybe)? PDS doesn't get traffic spikes on viral content because it's amortized by the app (which serves from its DB).
