Will PZ and Richard Carrier be giving presentations this year? They've done so at all of the previous Skepticons. I really enjoy Carrier's presentations. I always learn so many new things when he talks, I appreciate that he peppers his talks with humor, and I like to hear the odd cuss word or 5 thrown in here or there to put an exclamation point on some of his sentences. Plus, he's a great historian. And it seems likely that he might get into the mythicist view of Jesus (I'm really looking forward to that!)

I don't know if this is the proper forum in which to do this, but I think Ophelia Benson would make for an excellent speaker. She an extremely intelligent and well-spoken "gnu atheist" who writes her own blog, Butterflies & Wheels, where she takes on numerous false claims and tears them apart. She's well-known in the skeptic/atheist community and has spoken at other major conferences.
