Surely not I; but that is because its almost a pure hearing Dopers’ society.
Amoung the hearing, who is the smartest then?
me.
What on earth does hearing (or lack thereof) have to do with intelligence?
I respectfully submit that it is in no way me. I am far too confuzzled half the time to even be in the running.
Our Uncle Cecil, of course! 
This is one contest I know I have no chance of winning. 
Why can’t we have slightly stupid, yet adorable doper’s thread. Oh wait, I’m not even adorable.
My nominees are Veb and Tomndeb, I always look forward to reading their posts and their sheer breadth of knowledge astounds me.
I will also vote for DRY, because he will get all whiny on me if I don’t. 
“T’is certainly not I”, said the roo.
list might include
Omniscient
and
Chronos
There are plenty more but these two stand out, I always try to take in what they say, but I often get left behind too.
I don’t want to appear too creepy crawly but the mods are impressive too especially on their specialist areas.
Who says you’re not adorable Tater, tell me and I’ll send someone round to deal with 'em.
Who is the moderator in this forum? Slythe?
That’s my pick…Slythe is the smartest
Tomndebb.

I’ll cast another vote for Tomndebb. I’ve had the distinct pleasure (?) of being (diplomatically) rebuffed on a couple of occasions by Tom, and he was right. I hadn’t double-checked my answer, being fairly sure of myself. He has added many times more to my general knowledge of things than I have of his.
I’d also cast a vote for Dr. Fidelius, a learned individual indeed. With a definite sense of humour.
aha
Does anyone find it odd that only Kilgore Trout has said himself?
Anyways, I would say either myself (probably not bvery bloody likely) or Chronos.
Mean people, Casdave! Lots and lots of mean people!
Hmmmm…I noticed that you did nothing to dispute my slightly stupid remark.
I think Casdave is one smart Doper, too!
Coming from Kilgore, I’d say no.
Re your sig: different breeds, silly!
I’m going to have to agree with Slythe and nominate our own Cecil Adams. He counts too, doesn’t he?
I’m fairly new here–so I haven’t gotten much of a chance to call myself a ‘regular’ yet. So it’s always a bit of a surprise whenever I find an old thread that the Master has posted in. Even in all his crabbiness–he eminates IQ points left and right with a thirst for knowledge that will not be satiated!

(For some reason–I miss WallyM7 even though I wasn’t around while he was still alive and posting. The tributes to him on the TM homepage carry strong and sincere feelings.)
We miss him too.
I’ll throw in some Euro-Trash.
London_Calling and Spiny Norman, although a relative newbie and a longtime slacker respectively, are among the most eloquent and best informed Dopers, IMHO.
Since so few people are nominating themselves I’d just like to go ahead and nominate me, me me me me and ME!!
But IzzyR, oldscratch, lissener and Satan come in close second

I must argee, London_Calling definitly drips of IQ.
