I think I have done from time-to-time, but the problem is it's just too many matches. I'm too lazy to really think about which one was the best, especially if there were multiple ones that I liked, and I'm too lazy to go back and watch an entire match.
At the same time, I don't wish to taint the poll with a vote that isn't sincere. Ya'mean? I guess if there was an amazing five-star match on Raw, then I'd vote for it, no problem. Otherwise, I'm just too lazy to think about it.
Sorry.
