Add vote weighting for self-nominated Experts
I think that moderator votes on questions should count slightly more than non-moderator votes, say:
|--------|-------|
|<Non-Mod>|<Mod> |
|+5------|+6-----|
|-2------|-3-----|

I think that this should be the case because moderators (on average) most likely know better than the average user what a good question for SO is. Moderators are also less likely to hold a grudge than the average user (this is based on my very limited experience, feel free to comment if you believe otherwise), as they can get their rights revoked. While the average user might just go around downvoting things because they dislike a certain user, moderators are less likely to do so. The reason why I do not suggest more influential votes on answers is because mods aren't necessarily smarter, hence they don't neccessarily grade answers better (compared to the average user).
Taking BillTheLizard's suggestion, maybe every upvote you give...you get 1 rep?

Nope, a user can't really do that, regular or mod. There's a script detecting such patterns and reverses serial voting (either up or down) and if they do it repeatedly they might find themselves suspended.
