Hello atmosphere ! Over the last few weeks, a bunch of us have been collaborating on a new set of lexicons for publishing, indexing, and building out social features across long-form reading and writing apps ! 🧵1/7

Can you expand on the choice of block based document format over something human readable, and growing in popularity and usage because of #ai... why not Markdown? (i.e. like bsky posts, text+facets)

We don't define a content structure for documents. Platforms are are given the freedom to implement content in the way they see fit. For example, you could just create your own markdown lexicon, and use it in the `content` open union.

I understand I can do something different, in general, with lexicon. I'm curious to the choice to this specific block format for a proposed standard, over something like what Bsky did with text+facets My assumption is the choice is largely driven by the underlying pkgs/editors the apps here chose
