You are so right about the me-me-me excessive promo on social media, starting with Facebook.
Little we know that the 'user' is in fact the PRODUCT of these huge social media hubs.
The 'me' bait invites peeping robots in our homes, in our lives, to sell us ads - conspicuously touching the phrase we just spoke a minute ago. Hmm...
I don't use Facebook for my hobbies and business, as it's not even allowed to post 18+ stuff out there.
But I have separate accounts for school and family, which work pretty nice if you know how to insulate them. Anyway, the sneaky ads would find a way around, even after the introduction of GDPR.
A good place to chat (almost like in the good old times) is Gmail -- yes, another 'don't do evil' idealistic garage-team turned to evil mega-corporation -- however, I find that Gmail is a better/safer?/ place than Facebook.
About Twitter now, I use it extensively and exclusively for business, it worked pretty nice. Until about a year ago, when I've noticed that Twitter stealthily sandboxes adult content. Just log in as another user and look for your adult-account posts or hashtags. No results.
As a recommendation, I'd suggest you try Switter - switter.at - which is a Swiss-based social hub, adult friendly, and a great place to chat, to promote yourself and -yes- to communicate.
