Experimental Googling

It has recently come to light that one can, in fact, tell Google that you want to block a site's response to whatever query you might be making. All you need to do is click through to the site and then click back and click the block this site. So far I have banned Wikipedia, Ehow, and Yahoo's Question deally, plus Amazon. I find, your experience will -- no doubt be radically different -- found the searching experience ever so richer.
