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
I believe CoSo is a deliberate “trickle” and we like it that way.
