Being the ultimate fair, reasoned poster, I would, of course, make the perfect moderator.
Unfortunately, I’m not that insane.
Maybe next year. 
I toyed with the idea of becoming a mod. Then I realized I had more fun poking them with a stick, and I hate it when people poke me with a stick. Don’t you? I do.

Of all the people I never expected to hear that from!
You haven’t been paying attention to the ATGG threads, Knead – Esprix is a top.
Stop poking me! Ow! Quit it! MOM!
Esprix
No, he’s a top from Arkansas

Has anyone ever stepped down from being a mod or admin?
Yes. Two recent examples being Chronos and JillGat, IIRC.
But… why? What awaits them on the other side?
I think you’ve been around long here long enough, Blackeyes, that where the SDMB is concerned, there is no “other side” – there is only the Far Side.
