Yes agreed. I tried using Twitter to promote my work but I found Twitter to be even more toxic than Facebook in general and have since quit.

I'd argue that Reddit also does the same thing. On Reddit, you can always find a community that agrees with your radical thinking. Reddit also has a problem with groupthink where the upvoting system heavily rewards popular opinion, even if it's false.

In this day and age, I find that not participating in social networks makes me a happier and less radical person. If I do partake in them, I limit myself to generally harmless hobby and work-related communities.
