What is happening with the writing scene and social media right now?

Genuine question, sorry if this makes me sound ignorant. I've been writing for years but I'm trying to get into doing more stuff on social media now that I'm writing a novel - connecting with other authors, finding events, posting moodboards, posting art of my characters, normal social media stuff. I've just found though that social media has become really scattered in the last couple of years, especially with the writing community.

I know Twitter used to be the place to be socials-wise but.... yeah. I enjoy a bit of Reddit, mostly for questions and natter. BlueSky is nice but still small. Instagram is as-always image focused and since I don't post pictures of my mug the algorithm is a mess. I still don't know whether or not TikTok is collapsing or if people have recovered from Americans being kicked off for 10 minutes. Where is everyone hanging out now?
