Even better is the !sp bang, which is for StartPage (a google search proxy). This way you can get the Google results and still retain some privacy from Google. I also use !w (wikipedia) and !so (stackoverflow) bangs regularly. Finally, the search doesn't have to be prefix with these bangs, it just needs in to be in the search somewhere - I find it quicker to just append it to the end personally.
