Collarity CompassT, launched Monday, is a search engine that automatically ranks search results based on an individual's interests. By tracking the search terms, url choices, and selections of users and visitors, Collarity responds to a user's 'hot spot of interest' (i.e. query) with sites visited by expert-users in that area.

Levy Cohen, CEO and founder of Collarity, was nice to answer some of my questions; but as to how Collarity determines which results are considered successful for a given expert-user's search (versus sites they visit to evaluate, but decide are not useful/credible), he says that would dip into the secret sauce.
