Twitter is mostly useful for finding out what's going on. It's really easy to update, so it's often the first thing that gets updated when news breaks.
I started Twitter by following a bunch of UNL athletes. As time wears on, I realize I really don't need to see anything these folks post. Most of it is banter to each other, and frankly I don't care. I'm going to sh#t-can all my athlete "follows" and stick with coaches, reporters and some of the more funny feeds, like Fake Bo Pelini, Fake Tom Osborne, and some non-Husker stuff.
