What's the intended app/user etiquette for atproto apps with regards to publishing to the same lexicon? Like, say I build an atproto app, would it catch users by surprise if the wrote to the same records (e.g. posts, likes, etc?) that show up in the bsky.app? Or should my app be isolated?

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...

I'm thinking about how non-developers will feel about atproto. For example, will it take people by surprise that data entered into one app can show up somewhere else? More thoughts in this post.

rachelandrew.co.ukThis 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

notes.wesleyfinck.org@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.communityAre there any atproto apps that use records from competitors? This ecosystem won't feel open to me until @bsky.app uses something from outside the `app.bsky` namespace as part of its core experience

How hard would it be to replicate a community Slack installation to an ATProto lexicon so messages can be archived or sent to other application for indexing? Is there any community lexicons for this already?! cc @bmann.ca
