Okay, I get Facebook and My Space, but I am not sure about Twitter. It kind of reminds me of the status updates that are posted on Facebook, but without any profiles or fun stuff.
Several YA authors like to Twitter – Sarah Dessen and Maureen Johnson, for example.

Or you can search Twitter for your favorite authors (those are just two of mine) and other celebrities.
