Just yesterday I saw discontent with the lack of ”serious” discussion on Bsky meaning the pro networks have not migrated from X in that particular case.
Most of the complaints seem to be about lack of functionality on bsky. For example, no videos, and no lists (yet they are coming).
People are not content with Mastodon. X is becoming unbearable with spam and trolling. A lot of people are just quitting.
Nostr seems to be already in shape to answer these questions. Moderation tools are also at a level where I think we can start to take people in.
If we can target some specific niches, whole communities, that might be the most effective at this point.
