Here's what I would have responded in Seth's shoes (note: I'm a big Godin fan and think this is a killer opportunity but did not apply):
"Hi!
[this is a form letter- Given that I preach honesty in marketing, I figure I owe you that!]
I reviewed your app and am declining you for this opportunity. Overall, I was _incredibly_ impressed with the quality (and volume) of the applications. Unfortunately, because I am just one guy, I had to read through them quickly and go a lot on "gut feeling". I had to pass over some fabulous applications in favor of some slightly-more-fabulous ones. I'm sure I declined some great people. I'm sure I'll be interviewing some duds.
Due to the volume of apps, I can't send any personalized feedback on your application. I really wish I had the time to, but a guy's gotta sleep. Thanks again!"
