well, internet’s a big place. Facebook’s positive is “go where the people are”. It’s the only place to really find far off family or acquaintances to bump into.
I left for about 1.5 yrs around 2012-13 for Google+ full time -but came back. It’s ok. I know its flaws here.
Usenet would be great. It’s still around. You can telnet to BBS’ but the more obscure the more the echo.
Facebook does try to pair us up with antagonists. That’s a smart algorithmic move although it can be annoying sometimes.
