Cheryl and Kevin have a new website: Science Fiction Awards Watch.
The site has an extensive list of sf awards (hey, y'all haven't listed the Plunkett Award yet--though perhaps that's because it hasn't been awarded yet), along with detailed information about each award. You can view and make recommendations for awardworthy works, read a blog written by the site's contributors (on the main page), participate in polls, and so on. Looks like a good site, and I expect it to get even better over time as it acquires more data and commentary and info.
While I'm here, I may as well link to a couple of other relevant sites, even though I've probably mentioned them before:
