Before nominating a heavily active market user for moderator, you must think about the effect of their moderating duties on their market use, and vice versa.
Market:
Kerokerocola - I don't have any idea what happened/why he was demoted, but let's be serious here. He is as legit as they come, has proven to know how to mod effectively and efficiently and has good input on important issues.
Hahanerd - I don't really care that he has done stupid things in the past, just about everyone has. He always had the most mod logs, and proved himself global material.
I am hesitant to suggest either video, viou, or r2pleasent, mostly due to the fact that they are all here to make money, and moderator duties could limit their time to profit.
w000t for graphics mod - I don't even know if he is still active around here anymore. When I was here, and quite active he was always one of the more active users in the community and graphics section.
Why don't you just ask some old retired moderators to come back and mod? I know for a fact that Jimmy fits the SFO moderator position great, and that oldies like hamjam would make great mods.
Just my thoughts.
