GoodSearch donates $.01 to a charity of your choice for each search you conduct through its site. It's probably still making loads of money off all the ads it has, but still, why not contribute to charities while you surf the Internet?
Of course, now I have to choose a worthy charity. I suggest checking out Give.org's list of charities to find one that doesn't spend most of its money on calling you to ask for money and other administrative tasks.
And for all you Firefox fans, GoodSearch has an easy link for adding its search to your Firefox search bar.
