I sometimes start rambling about cool tips and tricks for Twitter, forgetting that I haven't really explained what the heck Twitter is — (OK Mom, this one's for you!). Basically, Twitter is based around one question and one question only — what are you doing? This free social messaging utility allows you to stay connected in real-time with friends, family, and co-workers via quick, frequent updates.

I can keep rambling on about how to use it, or you can watch this . . . a brilliant short video that explains it in a nutshell. But then again, it's really so simple that a nutshell is all you need it to be explained in . . . OK, OK, just watch and see what I mean! Also, let me know if you are a "Twitterer" below and what you like about it.
