Matt Gemmell:

The problem with responding publicly is that it’s soul-destroying. If you’re able to respond to reviews, you’ll be checking them obsessively, and you will respond. Worse, you’ll inevitably do so in a snitty, defensive way that pleads the value of your time, or the extremely modest investment the user has made, or your need to support your family, or the triumph of rational thinking. Don’t be that guy. Nobody cares, least of all some idiot sixteen-year-old, or Mr. I’m-An-Important-Lawyer. You’ll only lower and tarnish yourself. You’re screaming at the wind.

Another good piece about the App Store review process. Matt presents great argument for why public responses are not the answer.
