Idle observation:
Clippy gets consistently voted up on a lot of his comments because we find him amusing, and rarely gets downvoted because very few of his comments are substantive. We will end up looking extremely silly to new members if he gets enough karma to put him into the list of top contributors.
So... I guess it depends whether we pitch ourselves as shiny fun community or serious rationalist Singularitarians as to whether this is actually an issue.
A simple fix would be to not bother publishing a top contributors list.
