I've tweaked the Shablast algorithm tonight to improve relevancy. The new algorithm does a much better job of favoring informational material over sales pitches and other commercial material. It's not perfect, of course, but I think you'll find it much better.
My goal is to make Shablast the best research search engine. Have fun at Google when you want to buy something, but when you're out to do some research, I want Shablast to be #1.
