Ask HN: Which vertical search engines do you use?

I've put up some google custom search engines by collecting the 20-40 most active delicious taggers for a topic, e.g. clojure, and counting their tagged domains.
Works ok, a little better precision, lose some recall vs. generic google searches, but need to renew the list of domains pretty frequently

For people that don't know what a vertical search engine is:

Usually Google using the "site:" command for stackoverflow etc, since I'm satisfied with the way Google orders the results.

If once every month or so counts.
