Kurayami for his groundbreaking research on "general negativity".
I think Jagonath needs credit for his exceptional research on being a faggit.
I thought of a couple more.
Drugs - Prescription:
nolt
I don't think that I need to dig up any threads to prove this since he pretty much makes his living dealing with them. Whenever somebody makes an "omg i htink i oded on my dad's __________ omg omg am i going 2 die???" thread, nolt is always there to advise the (exceedingly dumb) person and tell them if they need to go to the hospital or not. He generally even gives them his phone number, which always impressed me.
I'm pretty sure that he's a pharmacist by trade.
I'd also nominate him for a bike expert since he knows a shitload about biking. He was a big help when I was choosing a bike last year.
Computers:
Mojotooth (I BELIEVE. I know it's mojoSomething, but I'm pretty sure it's mojotooth. Somebody else can confirm.)
He works for Intel. His knowledge of processor architecture goes far beyond the "hay i read anand stfu" crowd. He's made a number of really informative posts (some of which I had saved, but can't seem to find. TW's search fucking blows.) He even owned me once on the point that the P4 no longer has a 20 stage pipeline.
A Computers - DEC category should also be created just for Geck0 since he used to work there. But you won't do that because already the world has forgotten the greatest processors ever made. The world is a cruel, miserable place. Alas, poor DEC. So maligned for greatness.
By the way, you should change Piloting - Civilian (Helicopters) to (Rotary Wing) in order to sound more official.
