Having finished the sketches, you immediately post them to your website so you don't have to look at them anymore. In truth, you're glad to be rid of them... you almost regret asking in the first place. You guess you shouldn't be such a jerk about it, and you're sure the fans are just happy to be able to interact with the comic in this way, but is this seriously what they want to see? This is barely any better than the stuff you were posting to deliberately piss them off!
Predictably, your readers immediately start eating it up. Sometimes you despair for art.
