I'm on Twitter finally. My Twitter name is EconOfContempt. I'm not sure how I feel about Twitter yet. I'm definitely still learning. For a long time, I thought Twitter was a new kind of portable Instant Messenger that you had to have some sort of special cell phone service to use. I don't know why I thought that. An intern set me straight last month. What's really embarrassing is that even the New York Fed—one of the stuffiest, least "hip" institutions ever—beat me onto Twitter. Ouch.
