Nope, There's No Twitter "Successor"
Published several months ago by O'Brien Media:
Activity continues to decline over time:
Earlier this year about the UK: Twitter Falls to Lowest Traffic Levels in 5 Years (Start of Lockdowns), Down From More Than 37% to Only 6.5% (Facebook has made gains since then)
Just because X.com (Twitter rebranded) is rotting away - with some estimates that the majority of "users" (or activity/engagement) in it are now bots and real users leave in droves - doesn't mean that Twitter copycats/knockoffs/alternatives are gaining. Social control media is, in general, considered by more and more people to be "gross", a waste of time, and some governments/schools/families take steps to reduce its reach. It's bad for everybody, not just to kids. There's a lot of horrible abuse going on in social control media. Daniel Pocock wrote some articles explaining why social control media is fertile ground for online abuse.
The real aim ought not be to replace MElon's X.com (increasingly just a right-leaning botfarm); the aim should be convincing people that social control media is worse than a waste of time. It's time to leave social control media behind; all of it.
Grow up. Stop playing games. You lose your time, your money, probably even your sanity. █
