Twitter is a weird thing. Everyone, when they first hear about it is like "why???" I tried it and had no interest. Then, about 6 months later I started following a specific friend who was funny, and prolific. Then I would see him talking with other people using their @name and I would look them up and they were funny and interesting too. Gradually I built up from there.
Twitter is only as boring, or as interesting, as the people that you choose to follow.
