IMHO we can expect the Great Social Media Chase to continue.
Since a critical mass of people determined that Twitter was not THe Place, we have seen:

X --> Spoutible (pretty much over)
X --> Post.news - GONE
X --> Threads - stalled now people realize that Threads has no useful moderation, plus SPAM
X --> BlueSky - This Month's Thing
X --> Mastodon - trickle
X --> Discord - trickle
X --> CoSo - trickle

@gshevlin Threads might be stalled from a general user's perspective, but it is where a lot of the Writing Twitter and TTRPG Twitter folks have settled. The writers' community on Threads is very robust (and growing daily).

@ianthealy I can see that, since I am a writer. however, a number of the earlier arrivals have already found out the hard way about the utterly useless moderation process.
