Edit: As an aside, here is a way I think skill checks should not work. In a recent RPGA game, I had an idea for a way to use a skill in a skill challenge, but realized my character was pretty terrible at the skill. So I asked another player who had a good bonus with that skill to try and said I would aid him. But the DM said "Nope! Your idea, your roll. He can aid you." So naturally the check failed.

This is why I prefer player driven games. A good idea should be actually worth something. This is the kind of treatment that encourages players to not bother trying.
