I have never used twitter. The thing that made me completely uninterested in using it was mainly the 140 character limit. I get the impression that is something from the days of flip phones with tiny screens and having to type with a number keypad.
I figured as well that the 140 char limit would just make intelligent conversation impossible. So there would be zero content worth following.
At 10000 chars, maybe I'll sign up for an account - maybe.
