It grew from that to an easy way to make contact with local Twitts and to stay in touch with them (especially through the Tweet-ups) - also as a way of picking up snippets from journalists, comedians, etc, that I wanted to follow.
The beauty of Twitter is its -
- freedom: each user chooses who to follow: they are not restricted to following Twitts who follow them, and are not forced to follow their own followers, either
- flexibility: you can use Twitter on the Web, by SMS, through email, etc
- simplicity: the 140-character limit could hardly be easier!
- fun: try it and see!
