Interesting. I find a mix of fascinating sites I hadn't seen before (good), and off-topic sites with an obvious keyword relationship that the machine misunderstands (bad), plus a smattering of the usual sites, with an emphasis on keyword-in-domain.
Also, the search depth is very shallow. Some phrases only have 3 pages of results, others Lycos accused me of making up words (no results). Then I clicked image search for the same phrase and they had lots of results.
Looks like they're owned by an Indian company now, and have switched to their own results this year from piggy backing on Yahoo last year.
