I’m standing here at an Umphrey’s McGee show, and I can see the Kevin Browning’s — Umphrey’s sound guy — Twitter feed. Why does this matter? Because I can see the tweeds I’ve sent today that mention him and the band. This makes me feel rather presumptuous, even though that’s one of the points of Twitter. Still, I don’t like being that guy who @ mentions every celebrity-type he follows in hopes of getting a response.
