There should be a way to demote a question to non-permanent, meaning the question should remain open but after a couple of weeks after being answered (or inactive) it should be removed from any listing (incl. search engines), and only the creator and the people that already answered it can access it and anyone with the full url (e.g. no referer); that way it satifisfaces people that want a quick Q&A site and the people that want it as a wiki for programming. The other thing is that a question should never show anything less than -1 as its score, internally they may keep count of the downvotes but never show the user anything less than -1 because its too demoralizing for newcomers.
