@RobRenaud: It's not really that simple. Site after site has tried to allow certain kinds of list questions, generally in formats very close to this, then realized that they just don't work out - they tend to become unwieldy, unusable, outdated lists. (Yes, there are exceptions, but this is generally true.) This isn't really the community's fault, it's just the way things go with the StackExchange format. If they had something more like Google Moderator, for example, it might work better. But in the meantime, responsible communities avoid it. – Cascabel♦ Jun 17 '12 at 2:46
