Twitter: the good use of it

Twitter can be usefull if you don't use it too much. Too much twit is boring. Too little is not good either.

It comes down to not posting too often and not posting stuff that’s not interesting to others. Posting things like, “Going to the bathroom again.”, or “Heading home from work.” is likely to make people stop following your account — or even unsubscribe from Twitter altogether.
