I have been following the daily post (You should too, especially if you have a blog!) and usually just read their posts passivly, and rarely act on the advice. (Though I do sometimes.)
This is one of the rare times that I follow all of the advice in it: The post is about twitter, and why you should join.
You should read it, and heed it! I am now at twitter with the handle (That’s what it’s called, right? Handle?) @Teenmaker (It wasn’t used! Yay!)
