Bluenotes: Community Notes for ATProto
I'll briefly demonstrate Bluenotes, a fork of the Bluesky with Community Notes. Then I'll discuss a proposed "Open Community Notes" standard and lexicon for Community Notes on ATProto, and discuss challenges such as preserving contributor anonymity and defending against manipulation.

Bookmarking on ATProto
While building a bookmarking service on ATProto, the hardest question isn’t how to store a bookmark. It was defining what a bookmark actually is.

At Side Project Saturday (hosted by @val.town) I demoed a bookmarking service I'm building to learn more about ATProto and user-owned data. I've a bit stuck on bookmark lexicons and what belongs in a record. Thx to @awarm.space for suggesting I write down my questions donohoe.dev/2026/bookmark-lexicons-atprot…
What Is a Bookmark?
donohoe.devIs there interest in an ATProto service that given any URL, returns a unified backlink summary across the ecosystem? E.g., bookmarks on @semble.so , mentions on Bluesky or @standard.site , annotations in @margin.at, etc.
