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…

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...

In Which A Book Lexicon is Born

Thoughts on Bookmarking the Web - Henrique Dias
Yesterday I shared some atmospheric thoughts. One of the ideas was seeing which services do I use now that could be replaced. One of those is bookmarking. There’s two main contenders: Margin and Semble.
