Facebook is ok, it definitely filled with a much older age group and mostly I find people used it to talk to family from all over. But facebook groups for certain older topics like photography on film cameras for example have tons of members then other social media counterparts similar to talkbass it can have a better database. I find a lot of people from Indonesia use facebook still and are very helpful and active in bass guitar forms, so it is cool really seeing everyone from all over. Facebook I guess has expanded deep.
Instagram is OK, just follow accounts you like, avoid the newsfeed, always some toxic stuff. Creepy algorithm for sure.
Reddit - meh is ok, I never liked reddit in fact I kind of dislike it... but it's the few places you will hobby subs these days. I rarely used the other things and it tends to be an echo-chamber. I rarely go outside R/bass, R/swimming, R/Kendo or R/flyfishing and some other hobbies. Reddit gives me headache but again I like using it for those hobbies but there's always someone who generalizes an opinion, young users giving some awful advice, assuming things about people/famous people and system that runs on votes can be super bias... hence why reddit gets hate but I love it for sure for fishing subreddits a lot everyone is cool on there. But the extra anonymous you can be doesn't help credibility at all at times.
I have a twitter I just use it for seeing artist NEVER look at the news feed in that and I don't need to lol.
Do not have a Tiktok, I have no idea why my generation is so into it, and I refuse to every have one. No interest. I guess if you consider youtube one I have that but youtube is the wild west but it can be great for seeing local acts! I guess Steam is one but that's for PC gaming. Discord was a gaming communication now its used for groups, rarely used it outside of real life friends or college friends.
Hmm that's it for me, I honestly hate social media but I do enjoy Instagram seeing my friends and fan pages but thats all and Facebook groups and fan pages as well.
