IAR: Eurekster, We Have Found It
The labs at the portals are experimenting with personalization, but have not yet rolled out anything. Google even bought Kaltix when the startup was just a baby. Now Eurekster has taken the initiative and written a personalization engine that remembers what sites users liked (based on them not hitting the back button in under a minute), and tunes future results based on the selections. There is also a social networking aspect to Eurekster. Users can see friends' favorite searches. Obviously, privacy isn't going to be a big concern of Eureka users.
