Ask HN: Review my webapp for expiring domains

http://www.scoratic.com

It's a semi-curated list of domains that expire every day. I'd like other people's opinions on how useful is it compared to other similar services. Does the curation make things easier?

A brief explanation of the pretty basic rating system: It likes words, near words and wordlike words. It also prefers short over long, .com over everything else and it hates hyphens and numbers.

I have used it to snag a handful of dictionary names with it.
