In my opinion, twitter is just another silly thing to do on the www. I don't "Second life" I dont "chat" I don't "facebook" or whats-that-thing that NBC was so proud of finding sexual preditors on?
email and these boards are bad enough. What's even MORE irritiating, is you just get yourself into a set of user name/ password that you can remember, and the next thing ya know you run into some site that won't accept the length--too long or too short--or the numerical/ alpha makeup of your chosen moniker. Unbelieveably irritating.
