Pondering Twitter

I'm making a concerted effort to be more open-minded about social media.  My instinctive reaction to most of them is wariness, and thus far I've opted out because I simply don't need them.  Two pivotal conversations this morning have me reevaluating my position.  Pondering Twitter, I looked into the feed of a few bloggers I admire to see how they are using it, and I found this gem:

Dear spellcheck. No. When I tried to type “badass” I didn’t mean “bald ass” and WHY WOULD I.

Tee hee hee!

May I ask...
Do you use Twitter?
How do you use it?
Any recommendations or tips for a beginner?
Thus far, I have completely avoided it, but I would like to be more open-minded and better-informed about it. I'd love any feedback you would like to share!

Happy weekend, y'all!
