I know the topic of removing www.experts-echange.com has been beaten to death but having to type -site:www.experts-exchange.com is tedious. Even the ability to auto add strings to a query would solve this problem. I can probably wrap this into some wget mess but this seems like basic functionality many users would base their search engine of choice on. If you have discovered some easy method to do this for yourself please let me know.
I imagine there is a really slick toolbar that feeds google your text plus the additional strings you choose. There is some internal limit to the number of words and or operators Google searches process (with good reason I suppose).
