Clusters, Folders, yakkity-yak (Score 1)

I occasionally used Vivisimo's search engine years ago (I don't know if it had any association with Overture at the time).

It would take the search results and place them in categorized folders so that you could narrow down the search. Naturally, they picked the categories.

I suppose some filtering would be nice, but do I really need them to do something I should have done when I came up with my search parameters in the first place?
