I still like G+. There are enough interesting people posting there for it to be worth my while. Various sites get millions of visitors without offering real rewards, so that can't be all people want. Of course some will flock to any site that pays, but without good content they will not succeed. I'm not interested in games and celebrities, but lots of people are and they will go wherever they can find those.
I still believe that Steemit has potential. The technology is cool.
