How To Use Twitter

I still don't understand twitter completely. I know I can post what I am doing. I understand that I can follow people. I am currently following Cali Lewis because I like Geekbrief. I would like to know more.

That's very interesting. The use of cell phones is cool, but a lot of sites are starting to use cellular technology for users to update. How can Twitter compete with Myspace or Facebook?? http://www.chessvictory.com/chess-openings.htm
