I'm with Nathan Pippenger on this, the Barack Obama campaign emails have been weird lately
. I have my BlackBerry set up to forward work emails to my gmail account, so I can't tell who the sender is until I open the actual email, and in about 2/3rds of the cases with the Obama emails I'm worried that it's someone I've irritated. ("Yes or no, Erica?") Pippenger talks to Joe Trippi, who argues that the subject lines surely would have been optimized to increase user response, which is no doubt true--and here we are, talking about campaign spam--but maybe they should pay more attention to the kind of response they're getting.
