Good question. DMs are not great on nostr and group chats seem to be non-existant so far. I would like to see more development there because truthfully that is probably my base layer. I am not sure if nostr is ultimately the best tech for that...

In this case I am thinking mostly of notes and timelines. Threads with Q&A are also great. Job postings would also be excellent.

When I posted the note I was just referring to our ability to send words out and have others read them and reply. Breaking those communications down into categories wasn't on my mind.
