The results are surprisingly good. I did some searches for recipes, and frankly without the top 1000 you really start getting some fresh hits. Entries by real people, rather than sites raking up recipes for a hit.
Wow, I didn't know until today that Google doesn't serve more than the top 1000 hits. (A result of me thinking, "can't I just ask Google to show me the million-first through the million-tenth hits?)
First thing i used it for was recipes too! Started to find little blogs, or sites outside of north america, with some great Vegetarian recipes.
