During frag it was announced that there would be some Twitter only contests and such announced so I finally caved and created an account, however I think I may end up never being used here is why:
1. There is no need for Twitter it self to follow any one on twitter or any major site, why? Well because a) all twitter feeds can be monitored via RSS/Atom and b) most sites are really posting anything unique their.
2. URL shortening makes abuse too easy, twitters 140 character limit created this trend and it is a bad one.
3. You can't really use it to talk to your friends, your account has two modes, useless shut in, and public nothing to hide. You can send direct messages but at that point I might as well use email instead of trying to remember the dm @ syntax or using yet another client.
4. I don't want to post my life publicly, just to people I know.
