Dear Fringe Freaks:
If you didn't know, my Blogging Fringe site also has a presence on the chat / SMS / microblog thing that is Twitter:
www.twitter.com/bloggingfringe
What's Twitter? The service asks the question: What are you doing right now? You answer the question by using your phone via SMS, or a website, or an instant message client (which might also be on your phone). Once you get the updates in, other people can choose to "follow" you.
