My take on the "explaining atproto" discourse is that all the UX/filesystem/etc metaphors are still very verbose and that you can explain the same idea in a lot less words: It separates data from apps, so any app can use data from any other app. That fits in a tweet, with other sentences around it.

Lexicon Embeds Overview
ATProto’s inside out structure provides an opportunity for open, permissionless building on top of any component in the network, including its extensible data schema definition system, Lexicons. One of the opportunities this presents is users sharing their data and records with multiple apps. Those apps may be direct substitutions (different clients for microblogging say), or apps that use that data in a variety of ways, such as Popfeed an app which aggregates posts about a variety of media ty...

you know, the stuff that makes sense when you work on ATProto but makes zero sense for everyone else

atstats - ATProto Lexicon Usage
Imagining atproto as a post-app protocol starts with materializing the social filesystem – decomposing apps and their data into materials and instruments. For the time being, this guestbook is a good example where the display element is a material and the sign element is an instrument.

in any case, the end game is composing these little guys, whatever goes on behind the scenes. social components
This is partly why I think atproto needs a more convincing vision about being a post-app protocol. A future where atproto is a bunch of apps and each app governs their own lexicon diminishes a lot of its potential in the long-term.

yeah i think i might actually, theres a very interesting story here that the main thing that matters is a focal point around which consensus over a lexicon can get formed

Very glad you asked! Bluesky runs on tech called AT Protocol, which lets you use that same account on sites like rpg.actor via process called OAuth which keeps your password away from our server. Login actually takes you to a bsky.social page that lists what read / write our site wants in to use:
the point of atproto is to make locked-open apps. apps which are constrained such that they cannot be e.g. bought by billionaires and ruined. yes, doing non-atproto things "enables app developers to do more". yes, non-atproto is "more intuitive" and "it sucks" when you hit atproto's limits.
while the permissionlessness vector of atproto will certainly enable new things we can't imagine the pattern of "____ but on atproto" is key for taking our daily lives back. a framing i prefer is "i can now do {boringDailyLifeThing} without {shittyExtractiveApp}"

i would like to see more atproto apps that aren’t just “already popular app, but on atproto”
@atpota.to and @dame.is, we were talking about making an ATProto-powered app directory on the community forum and someone found your atproto.garden and some records lying around. Are you interested in sharing your lexicons or talking about what a simple directory lexicon might look like?

discourse.atprotocol.communityMy "Introduction to #ATProto" blog post that I've been working on for some time is ready 🙂 It goes through things like records, lexicons, DIDs, then PDS/AppView etc. and how it all works together. Let me know if anything is wrong! More parts later, with the Fedi comparisons & misconceptions etc.
