So old

Apparently all my friends are on something called Twitter, which is cute. (not Twitter itself but that fact that my friends are there being all funny and shit.) I can’t fathom what Twitter is or why people join, only that your cyber pals are referred to as “followers” and the site boasts that you can find someone to follow. Is this the next evolutionary step of Friendster to MySpace to Facebook? I’m confused by all this 21st ephemera, but what else is new?
