I was tempted to agree with Mammuthus, bowing out with the observations that I've only been here a few months, and that there are just too many good posters. As I noted above, a strong case can be made for every nomination in this thread.
But the quality and quantity of RAZD's posts stand out. I agree with him often; when I don't, I can understand and respect his position.
RAZD supports his positions more thoroughly than most, providing not only vigorous thought but a wealth of citations and links as well. In some threads, his heavy lifting in rebutting drive-through obscurantists left me in awe of his energy, esp. after I saw he has a few miles on his odometer
Holmes and RAZD were a coin toss apart: everything I've said of RAZD, I could say of Holmes, but Holmes helped me to decide with his own vote.
Congratulations to everyone, Admins strongly included. EvC is a remarkable forum.
