Too tired to search for a small study that I read about a few days ago that dealt with the usage of social media sites by small businesses. If I'm recalling correctly, Facebook was close to 50%, Linkedin was 7%, and Twitter was around 3%.
There's another article out there somewhere that mentioned that a low percentage of Twitter users produce the most tweets, by a very large margin.
Almost all of the important people/sites that I follow in my industry on Twitter do nothing more than link to their own content.
I do appreciate that on some days, but I guess I was hoping for something more when I signed up on there. A lot of what I'm exposed to on Twitter just seems to be done in an automated fashion.
