I've mentioned in a previous post my confusion as to the
popularity of Twitter. This is exactly what I was talking
I will say, that recently, after attending SxSW, I figured out the value of Twitter. Before arriving in Austin, I cleaned out my friends list, and now only follow people I know, especially those that attended SxSW. This made it easy to figure out where people were, and how to meet up with them. So, it's no longer a mystery to me, however, I still don't spend much time with it either.
