A handful of search engines made their debut or introduced new products at Demo in Palm Desert, Calif.: Circos.com, Delver (formerly Semingo), HealthPricer, Silobreaker, Jodange and Eyealike, all of which have varying degrees of attractiveness to Google. I believe some have more appeal than others. Circos.com is a social search application that gauges the content of each search and prioritizes results based on users' preferences and needs. Such a hive-mind-oriented technology could help Google better target ads for users.
