I attended the NFAIS* Conference in Philadelphia this week. It was an excellent conference. One of the topics was: What should search engines do besides search? Here's one that may have found a way to add value. Clusty Yes, I know, we've seen clustered search results before and they were just confusing. This seems to have overcome that hurdle. This is a product of Vivisimo, which also now has this same folder approach instead of that spider thing they used to return. (You can still see what clustered results look like w/o folders or hit numbers at Mooter.)
* It used to stand for National Federation of Abstracting and Indexing Services but now it's just NFAIS.
