What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

Building More Resilient Local-First Software with atproto | jakelazaroff.com
atproto has the potential to become a rock-solid replacement for the most fragile part of any local-first app: the sync server.

The killer app of atproto is interop

some thoughts on atproto as a post-app paradigm
Ecosystem Plugins
notes.wesleyfinck.orgImagining 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
Sign of a post-app economy forming around atproto
Erlend Sogge Heggen
As @awarm.space pointed out in the replies, ‘traffic’ was never the real goal for authors. What we want is for our stuff to be read, and expand-on-click article embeds enables that, with AT-net metrics. The prospect of mutual syndication is the entire premise of our shared presence here on atproto.
Updated my @leaflet.pub post with a few more ATProto apps I've come across: ichris.leaflet.pub
Other Apps to Use with Bluesky that Aren't the Social Network We Know as Bluesky - Shouting Into the Void
ichris.leaflet.pubThis 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
