ok you must not have a twitter account.
i use mine mostly to follow websites, blogs, news sources and yes celebrities, but its not like they post shit like "im sittin on the couch watchin football"
most of the tweets I see are actually interesting stuff about tours, albums and stuff I am actually interested in. it's basically a personalized news feed that only gives you info on stuff you choose.
thats how i use my twitter anyways, and I haven't written a tweet in weeks.
