I joined facebook in 2008. Somewhere along the line, I was asked by someone pretty well known to join a writer's groups. She promised me a contract and profits. I did.
The nastiness and vindictiveness in that group and the general spitefulness and meaness made me leave Facebook for Google Plus when it opened in 2011. I faced much of the same. With a following of some 38,000 people, I decided 5 years in just to block mean people and to delete their comments.
My entire world changed. Since that day, I have enjoyed social media. I'm also extremely grateful for it. I can now seee people's political opinions, their morals, thei idiotic belief systems, and I don't have anything to do with these people.
I have now made real friends who share my values.:)
