Found a new Google tool today called Custom Search Engine that might be useful.

I’ve for some time now wanted to always exclude certain domains from my search results since they are of no use to me. For example, I will never pay for experts-exchange.com so results from that domain are just a nuisanse to me. So now I’ve created my own search that always exclude unwanted domains. It only excludes experts-exchange.com right now, but I’ll probably add more as I find them.
