Another option is to go like email and let people post with multiple alternative encodings of their content, plaintext, md, and html…
Personally I really like what you can do with formatting in markdown in scuttlebutt.
More I think there’s lots of interesting things you could do with collaborative document creation using CDRT’s where you scoped who could contribute based on your social graph. That kind of document would need some formatting.
Sure, I agree. I think we should have other standard formats, but in other contexts (and probably other apps dedicated to them -- not that they couldn't be merged into "social" apps too if client developers wanted), using other event kinds, not the basic most simple Twitter-like kind-1 notes.
+1 for alternative encodings, using a tag as an suggested by jb55.
To improve interoperability it is the sender client that should manage the plaintext version.
