Web Clusters: Users Visit Six Sites

PSKF points to a British report that says "Web users now have almost 76 million sites to choose from, yet most only visit six on a regular basis." This is something we talked about with Behavior Insider last month - instead of buying ads on random places online, it would be more effective to "roadblock" the websites that make up these clusters. The challenge, of course, is to figure out what these sites are.
