Keyword affinity for news.ycombinator.com: hacker news: 1700.0x, whois: 25.0x, google analytics: 19.0x, google voice: 14.0x, tiger woods: 7.4x, avatar: 7.4x, brittany murphy: 4.6x, amazon: 1.9x So Google thinks Hacker News readers 4.6x more likely than the average internet user to search for "brittany murphy"? I wonder how accurate this stuff is. It'd interesting if pg (or anyone else with a site large enough to show up) could confirm/deny the accuracy of the results...
