Here are some oldies, but goodies:
IC - the default target for people trying to prove themselves (probably because he's so nice), but he's still a damn fine poster.
Papa Shango - can still knock out some damn fine work in M&T.
Razor - Never praised the guy, but here it is; his critical thinking skills are on point. I wouldn't mind going a few rounds with him Socrates style so we could come up with some profound and fundamental truths.
Lee - He knows how to keep it short and simple; I wish all posts were like his.
