So I typically don't have much use for the more advanced Google search tips. I almost always find exactly what I want with a simple query. However - something has been bugging me for a while now and I finally got off my butt to learn how to correct it.
If you have done any searching for technical type matters (like the one I just did: javascript radio), than you have probably ran across Experts-Exchange. This is a site that provides technical answers, but you have to sign up before you see the result. I don't know why but this bugs the hell out of me. The entire domain, as far as I am concerned, is completely useless. As it stands, I can't even get the "View Solution" button to work right now.
Turns out there is a trivial way to hide this site from your results. I just added:
-site:experts-exchange.com
And when I searched again, it was removed from the results.
Now if I can just find a way to make that the default, I'd be even happier. There must be a way to tweak the Google Toolbar for Firefox to get the same results.
