I have left Facebook for anything meaningful, but I have continued to post photos of my cats and flowers, and news updates on what's flowering in the garden. I don't try to have "serious" conversations with anyone there, however. I still belong to several groups there, and they are very niche and topic oriented, so we stay *"on topic,"I and I guess FB is still OK for that, in some hobbyist sort of way.

I completely avoid politics on Facebook because I don't function well in an environment where someone is unable to appreciate (and work with) the positive aspects of both sides the political spectrum. I guess I'm a bit of a Buddhist at heart, in that I believe that no perspective can be 100% right OR 100% wrong... and I seek out the right parts rather than the wrong parts. That doesn't work well for those who'd rather engage in a verbal brawl than find actual solutions.
