Search Engine Journal reports that Technorati added an "authority slider" to its search engine. The search slider enables you to set the level "authority" you want to filter by; the filters include (1) "Any authority" that will show all results, (2) A little authority that will show results from blogs with at least one link, (3) Some authority that will show results from blogs with a handful of links and (4) A lot of authority that will show results from blogs with hundreds of links.
Dave Sifry of Technorati posts in his State of the Blogosphere, February 2006 Part 2: Beyond Search blog entry, that the "Filter By Authority" "in no way should this imply a value judgment." Technorati uses link data to determine what is an "authority" and what is not. They are asking for feedback on this feature here.
