But seriously, Stack Exchange thrives because of its focus (which is maintained in large part by its culture of moderation, though only a small part of that is done by actual "moderators"; the community self-polices pretty well).

This contest is aimed at catching posts that would be closed before they're posted. Ideally we'll get a classifier that lets us give guidance to the askers. Better education of new/confused/troublesome users, leading to better posts, and fewer closed questions overall.
