Makes sense. It doesn't look like it's been abused too much, if at all; most of the categories seem to have a reasonable competition going on.
The last time I hosted my own awards, which was in 2003, this group of writers came in and totally found a way around my polls, which I thought you couldn't vote in more than once a day (turns out you could if you cleared your cookies or dialed-up again or something... it took some effort, but it was possible), and rigged them so that they won every category they were nominated in. I'd never even heard of them before then, so I knew they weren't just uber-popular and guaranteed to get a lot of votes. I was so pissed, that was the last time I even bothered.
