While it says on the tin, at the it says on the tinStack Overflow blog: A Theory of Moderation, that the moderators should do as little as possible, we're having an election because the site has "grown and it would be nice to have a larger team" (paraphrasing terdon from chat), so I assume that there'll be moderator tasks for you to do.
If you plan on spending about the same amount of time on U&L, what other U&L activities (such as Asking, Answering, Editing, or Reviewing) that you currently do today do you see yourself doing less of when as a moderator? Valid answers include "spending more time on U&L", of course!
