Twitter is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?
It is quick, simple and immediate. You do not even have to have your browser open. I use a Adobe Air application called "twhirl".
There are other apps available, do a search on Google and choose the one you like.
Twitter can be used for many things, just to let your friends know what you are doing or going to do. It has obvious benefits for business, like getting news out quickly.
If you want to follow me on Twitter, my user name is "mcvtoo".
