I love this! And am totally going to use it. Removing the top "thousand sites" removes pretty much all the sites I WISH I could have filtered from my Google results anyhow (ehow, w3schools, etc). One request: please keep the search text in the form field after clicking "search". Just so users can search the same thing multiple times with different values in the "Remove the top" drop-down.
