I would never degrade myself to ever visit or use any form of “social media”.
I THINK IT’S THE STUPIDEST THING EVER INVENTED!
I'd suggest that Free Republic meets the definition of "social media."
I used to have the identical opinion, but I have found that Twitter is not just a bunch of middle school girls saying, "OMG, I just saw Johnny at the mall." You only "follow" (i.e., see the postings from) people you wish to follow. So, I follow conservatives such as Jonah Goldberg. If I have something I believe to be pertinent or humorous, I tweet it to my followers.
It's not that different from FreeRepublic in that you are sharing communication with like-minded people. There are also some interesting flame wars between the Obamabots and the non-KoolAid drinkers.
Of course, you have to express yourself in 140 characters or less (very difficult) although one can link to news items, etc. I'm not proselytizing--just offering up some information.
