Eh, it depends, and you have to be very careful about falling into obsessing about likes and dislikes. To give my experience with different social media:
Facebook: I've know people with facebook friends and likes in the triple digits, while I rarely broke above the double digits. Now most people have moved on, and I only use it to contact older relatives.
Twitter: Don't have an account, don't want one.
Reddit: There's some nice communities if you avoid the biggest subs. Not a good place for any sense of "belonging".
Small forums: Some good experiences, some bad experiences. Small random forums, often centered on a hobby or project are the ones I like the most. The only real "internet friends" I've ever made are from these places.
Linkedin: Useful at best, facebook lite at worst.
MMOs: A cousin was hooked to WoW, but I never got into any of them long-term.
KYM: I'd be surprised if I was. I spend a lot of time complaining, and when I'm not, I'm preaching. Plus, I still hold a small grudge against what remains of the community for what it became a few years ago
Still, the images and comments can be funny, and I can say things here that I don't say anywhere else, all the while there's few enough people that comments aren't usually drowned out.
I mainly stick to e-mails or zoom for any real conversations, but I hope you eventually find a community you'll feel comfortable in.
