i'd like to see a wishlist of things we'd like documented, so that those wonderful people who have been assimilated into the Site documentation clan never run out of ideas. not that they do, i suspect, but it would also provide a method of feedback that, if properly implemented, could prevent some things from being requested eighty nine thousand times. also, it could include prioritization functionality so that users have some idea what might get documented soon versus what's never going to manage to get written up.
i'd also suggest a SDC recruitment center ("Congratulations! If your name appears on this list, you've volunteered to work for us!"), but i'm afraid i know someone who'd be on it as soon as he had enough experience, and frankly, perlmonks has already sucked out too much of my brain..
