Do you Twitter? If so I Want your Feedback

I’m doing some research on social networking and in particular Twitter. So if you Twitter please forward me your thoughts or post your comments on it here. I’m curious to know how it affects your daily routine, how many of your friends or colleagues use it, do you use it with some mobile technology etc. Thanks.

Revised: I’ve decided to expand my focus on this questions to other social networking sites such as Facebook, MySpace, LiveJournal or blogs in general, Stumbleupon, Flickr etc.
