I recently started using Twitter. I'm still getting used to it, and the whole thing is a little weird to me, but I'm pretty sure I like it. It's interesting to follow user updates/tweets and see what people are up to during the day. Some people just post links to things they're looking at or that inspire them. Other people just write what they're doing at that moment. Some people forget they have twitter for a few days at a time.
