I suspect social media is slowly losing steam in general. Post-social media could look like private groups, the sort of groups that facilitate offline activity. Which is sort of a return to how some things like this functioned before the Public Square social media (or however you want to call it).

You mean like during the time of BBS era of the internet. Smaller special interest groups. More exclusive and homogenous.
Yeah, I think we are already seeing this with private messaging groups, matrix, discord etc. Could be based on interest or local community, friendship groups. I think a message board revival would be amazing too. These places don't even really need to be private, the barrier of entry is having an interest in the topic and staying on-topic.
