Is Anyone Using Twitter?

I recently opened a Twitter account at the behest of my son.  I have seen that some of you have “Follow Me On Twitter” postings on your websites and blogs.  I don’t have much experience with it yet and would be interested in finding out what experiences you have had with it and how you are using it. 

For those of you who don’t know what Twitter is, it is a free micro-blogging, social networking site that lets you let people know what is going on with you, your niches or anything else in a few short sentences. 

I have only used it a little bit, but will see how it goes.  So Folow Me On Twitter
