Most people who roleplay probably don't post here. Which is not a slam against enworld.
It's also more difficult to quantify. You can describe your cool adventures and stuff, but good role-playing is one of the things where you really kind of have to be there to appreciate. You don't really get to talk about the role-playing - instead you're getting the narrative. That's not to say it can't be done, it's just not as easy when you're dealing with numbers and math.
Optimizing is very quantifiable. "Hey, I just noticed that a furfflemaker with a left-handed persmiddle can get a third swizzle if they also take the milliputting and quantumizing feats."
Woah! That's way OP. You should never be able to get a third swizzle.
