Captcha, but not for bots, for humans.

The way I found reddit was from a link in pg's essays. And boy was reddit good when pg first linked to it. So we need a place where the only people are the kind who would voluntarily read something like pg or steve yegge.

Perhaps a simple logic puzzle wrapped inside a question about programming? That would require both factual knowledge of programming and at least a modicum of thinking ability.

That's your captcha for posts and voting permissions.

The problem I see is how to generate the captcha question/reply pairs. Perhaps something wiki style?

For each problem in Project Euler there is a forum that is open only after you solve it. One of the hard ones has "First!" comment in there.
