More signs of discriminating when building a blog search index.

“Instead of crawling, Ask Blog & Feed Search harnesses the subscription data of hundreds of thousands of real people who use Bloglines, the #1 online feed reader, to create our search index. In the absence of a mature link structure, people provide the best way to discover the freshest, highest quality feeds — information that isn’t exposed to crawlers. In addition, this “collective human intelligence” provides a natural defense against spam, as people typically do not subscribe to low quality content.”
