This is the toughest round yet. These are two of my favorites right there, I really should start fixing this contest.
Carl has been doing a wonderful job as a moderator, often bringing another point of view to the discussion. I value his input greatly although he sometimes has little passive aggressive periods He's also very active in the community and knows our users a great deal. Which in turn means he knows how to approach delicate situations effectively.
On the other hand, I consider Rol to be an integral part of the VGC community. I always enjoy reading his threads and of course the response they generate. He's a famous Nintendo poster but for all the right reasons, he knows Ninty isn't perfect and isn't afraid to criticize their moves which is refreshing compared to the "my-choice-company-can-do-no-wrong" attitude we see so often. He's also provide some great insights in the mod thread.
With that, I'll be voting for RolStoppable but I'll be happy with whoever wins the round.
