Do you folks think Reddit could improve with a more 'detailed' upvote/downvote mechanism?

..something like a combination of how Slashdot's mod points work and the current system? I haven't spent time refining the idea, because I know it's not going to be implemented with reddit's current roadmap.

I think it would be neat if I could upvote/downvote the way we currently do, but we also had a limited number of 'mod points' (to borrow Slashdot's term) to help particularly contributing content to float to the top.
