Very frankly, twitter is half an idea, and while the half is pretty good, the lack of the second half makes it not keep users.

Even crappy TV shows grow on you. Twitter does not. It's like IRC - there is a large and dedicated group of people that use it, but it's not mainstream. Same with twitter, it will grow to a certain level, but it will be like IRC.

Many people just don't need the constant stream of textual information, and when they get that that's all twitter is, there is no point in staying on.
