Guilty! Except I don't tweet. I just follow and observe the banter among the masses. Most of my 200+ follows are news-related (sports, politics, music & arts, etc) for info. gathering.
Your point is valid though, sarcasm or not. The social networking phenomenon is one giant stalk-fest, for better and worse.
haha I follow most of the team, and every once in awhile even tweet at them
but I actually see them on occasion, or have classes with a few.
and yea, it can be a stalk-fest, but at least you can get some updates that never seem to come out anywhere else
