The Bluesky ecosystem has the juice (ATProto for normies)

An explanation for people who don't care about software protocols

Bluesky is built on top of a new software protocol - https://atproto.com/ - for building distributed networks. If you're coming to Bluesky from X with zero care about the underlying tech, that's chill. Right now, your experience is basically the same. Under the hood, Bluesky is hosting your account information and everything. Just like X would.

So, so far, same same. But here's where it starts getting cool.

You see a photo sharing app that's competing with Instagram. You take a look, and look - you can log directly into it using your Bluesky account. No new password. No new account creation. Then you find a blogging site. Your blog is already reserved at your Bluesky handle. When you want to add an image to your first post, your photo sharing app uploads show up as options. A podcast app, a Goodreads alternative, a neighborhood forum - each one recognizes you instantly. And none of these are made by Bluesky.

Think of it like email. You can have a Gmail account and send a message to someone on Outlook. Nobody owns "email." The AT Protocol is trying to do that for social media. Your identity is yours, and every app knows it.

It's already happening. AT Proto stuff that I actually use. And to be clear - these are all built by separate individuals of groups of people. It's the protocol that links it all together.

  • Plyr.fm - Music upload and streaming service based.
  • pckt — What I'm using to write this. Where you are likely reading this. Blogging platform. Your posts live on your personal data server.
  • Leaflet — Long-form publishing. Can already read pckt posts and vice versa.
  • Tangled — Decentralized GitHub. Just raised €3.8M.
  • Graze.social - BYOBluesky algorithm? Don't like what the main feed is sending you? Build a new feed, or find feeds that better suite your wants.

All of these apps recognize your single Bluesky identity. No new accounts. No new passwords. Your data moves with you.

If you want to try it, join Bluesky - it's free and open. And if you want to nerd out about the protocol stuff, hit me up.
