What are you doing? Twittering. Twitter was all the rage at SXSW Interactive this year. Think instant messenger in real time, all the time. Everything you want to say in 140 characters. Basically, you use it to post very short messages about your every move. At first it seemed silly – how much did I really need to know about what other people are up to? Then, I realized that there were entire events being scheduled on Twitter that I didn’t even know about. Try it – you’ll see what I mean.
