I was very much into Facebook until it went south. Honestly, I was using it for two main purposes in the beginning around 2009; to find people I'd lost touch with over the years and to promote my creative endeavors (such as spreading the word about shows I was playing, my design work, video projects, etc.).
As Facebook continually morphed its algorithms, it became harder to use it for self-promotion. Facebook wants everyone to pay for that feature now, so anything it detects as such gets de-boosted. The same now goes for the newsfeed. You don't see what you want to see, you see what Facebook wants you to see. For those reasons and the recent privacy scandal, I've greatly reduced my use of it at the personal level. The same goes for Instagram (now owned by Facebook), which has become rife with ads and adverse algorithms. I currently have about 3,000 Facebook friends (after purging about 1,000 last year) and 2,000 Instagram followers, but the engagement for both is generally about five percent or less.
I continue to be active on YouTube for the time being, but they are making it harder than ever to grow my channel and earn revenue. I'm currently at a little over 10,000 subscribers on YouTube with an engagement of around 8 percent.
In my opinion, all these platforms are squashing anything that doesn't match with their socio-political and business models, which is finally creating backlash among average users.
This is where places like TWT might have the opportunity to bounce back in the wake. I like TWT because it is more 'local' and specific to my life interests, if that makes sense. It's primarily a bunch of friendly motorcyclists within several hundred miles of my location sharing useful information on a regular basis. It is also comprised generally of people I identify with culturally, which counts for a lot. Everyone is also equally visible on TWT. I think forums might make a comeback over the next few years for that reason alone. TWT is a place where we don't have to worry about being de-boosted or shadow-banned. So long as we post according to the established rules, one user's post is just as visible as another's.
