Blekko Aims to Slash Away Shady Search Results

Blekko, a new search engine in the works since 2007, launched as a public beta Monday. Like Wikipedia, the site leverages the work of volunteers; in Blekko's case, they categorize the Web in an effort to weed out malware-ridden and spam sites. Curators do this by creating slashtags for topics they like, such as "U2/music," for example.
