"My favorite example is the search engine GoodSearch.com. The idea behind this excellent search engine (powered by Yahoo) is simple and brilliant — 50% of all ad revenue generated from the site is donated to the charity of the user's choice, and the money GoodSearch donates comes from its advertisers, so it doesn't cost the users or the organizations a penny."
