A little step: working on an AppView and small Lexicon to make contribution information modular and transparent - so it is easier to signal if you're looking for support, and how to provide it; will have the repo public soon, and hope to get the alpha public later this week - feedback welcome!

Apps are too complex so maybe features should be ownable and tradable

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...

Introduction | HappyView
HappyView is the best way to build an AppView for the atproto. Upload your lexicon schemas and get a fully functional AppView, complete with XRPC endpoints, OAuth, real-time network sync, and historical backfill, without writing a single line of server code.

Think it's looking a lot nicer :) Got comments going too, I used @leaflet.pub's lexicon seems to work well for general use case of threaded comments on the atmosphere, thanks friends! We might actually launch this thing yet! Now the hard part: AppViews!
Lexicon suggestions for reader apps on AT Proto (such as @leaflet.pub Reader and @skyreader.app): - storing the reading status of a given URL - “liking” or “recommending” an URL - public (and when permissioned data will be out, private, or access controlled) folders to organize subscriptions
does a @semble.so <-> @lexidraw.app integration interest anyone 👀

Totally! Graph view will also be really useful for creating these, something we discussed in Vancouver @chrisshank.com @wesleyfinck.org @pouriade.com
Hey @danabra.mov, I’m working on a new labeler for arbitrary atproto records. I’d like lexicon owners to be able to suggest how to render their lexicons in the app. I’m thinking maybe @inlay.at components as sidecars?

I'm working on a new labeler software (i.e. an alternative to Ozone) and this really feels like the right way for these things to work. 😎 #atproto
I've been thinking a lot lately about how lexicon authors could help app developers understand intent. #atproto trezy.codes/blog/what-if-lexicons-knew-ho…

has anyone thought about the multi repo feed yet or are we still in the era of "this is a <app.bsky.*> viewer" and "this is a <site.standard.*> viewer"
this is really great, and i'm glad that you're thinking about it!! I just started building @atmobb.app and wanted to build a way for it to pull in topics from similar forums and landed on subscribing to a "topic" for those forums. very excited to see what happens!!
I finally put some ideas into words about the artist focused app that I would like to build on atproto. I am looking for collaborators, especially artists and UI designers.
Artist app diary (1): the general idea
hilkeu.leaflet.pubrelated: for a number of use cases on atproto, the challenge has shifted from 'how do i get people to use my app' to 'how do i get people to use my lexicon' this also shifts what prototype apps even are
dame
in my experience there is now room to “vibecode” a prototype, evolve it into a more serious app, and then down the road refactor it into something that is more professional, organized, and sustainable previous AI models couldn’t handle large refactors like this, but they now can with human aide
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
