If you pronounce it "own", you may as well just say it. I do not say "pwn" unless I am clearly being a super-nerdy-overthetop gamer, and when I do, I will say it in the proper wrong way.
Also, there are several possible origins of the word. Just 'cuz a guy with a website that has "pwn" in the name, does not make him an expert on the word.
Also, Adam Sessler, host of X-Play, pronounces it as "Pone". Him, plus the ultimate powers of Blizzard entertainment and South Park, establish it as the canon form, IMO.
