I am legitimately shocked that I got NO LOVE in this thread. Oh well, I figure it is due to the fact that I use words many of you may not understand.
Xfear is extremely bright, but he swears so much I think his intelligence gets lost in his anger. That's my personal opinion, as I rarely swear.
Shockey is very intelligent, and he doesn't flaunt it or brag about it, nor does he intentionally try to draw attention to it the way Sly and I do.
Jake's intelligence is a bi-product of his calm demeanor. He doesn't let anything or anybody appear to get the best of him, and often times it's the person who remains calmest in a debate who ends up winning it, because they maintain all of the faculties.
Echelon is a bright one as well, and he's my kind of bright, because he's not afraid to do research. He doesn't claim to the the end-all of human existance in terms of knowledge - but he knows where to go for an answer.
Shadowmancer is another one I have a deep respect for in terms of intelligence. Like many smart people on the boards (myself included) he isn't void of arrogance, and as a result he comes off very confident.
SlyFox is the rear view mirror of intelligence - objects may appear smarter than they are. That's not a knock on Sly - the man is damn smart, but his debate skills are so polished I don't know how much of what he says is intelligence and how much is pure communication skills. He is able to totally dissect somebody's arguement, even if it takes the points out of context, and obliterate each point calmly. Plus, unlike some less-successful debators, he doesn't blow his load on the first arguement - he asks you questions about your point in an attempt to get you to say something that you'll end up paying for. The result is the inevitable surrender of "well, that's just your opinion, Sly."
I also want to offer the "underrated" intelligence award to Polley. I had the pleasure of debuting the Master Debator thread with Polley, and despite winning it, I had a VERY hard time because Polley brought up and researched some excellent points. I have also enjoyed seeing him involved in the music and film threads.
We also need to show love to RVDGurl, Kasey, and Eternal Dragon. Seriously, if some of the assholes of the world who had stereotypes of wrestling fans being stupid or one-dimensional came to these boards to read some of our debates, I think they'd be impressed by the group of us.
