It's the youths driving things. Drives me nuts that so many of our younger relatives/friends are sending us Instagram and TikTok shit.
Meanwhile I've spent the past month getting a bunch of stuff setup on BlueSky, Threads, and Mastodon, because the project I'm working on has a lot of long form stuff that is better suited to those. Unfortunately the target demographic can't fucking make up its mind between those three as an alternative to twitter, so I'm also having to maintain a small twitter footprint as well. But twitter continues to get worse and worse with porn/spam and I'm seeing more brands using the other platforms in parallel to twitter, so I'm able to do a lot less and use it solely to point people to other platforms or websites.
It feels like I'm seeing a lot more academics/writers on Threads. I actually enjoy the conversations on Threads, as there's some cool people on there, and it feels kind of like what twitter was really early on.
BlueSky is a literal twitter clone, but they fucked up by not scaling up faster than they did (the backers had the money, they should have ditched the invite shit much, much earlier).
Mastodon has the most technically advanced client (including browser-based/web), but it still confuses some people. With that said, the way the groups stuff works, once you know what you are doing, if you hit the right groups, it's pretty easy to acquire hundreds of followers at a time.
