GoodSearch.com is a new search engine that donates half its revenue -- about a penny per search -- to the charities of your choice. In the "enter your charity here" box, you can either enter the name of your favorite charity or search by keyword: pro-choice, environment, women, children, education, homeless, etc...
You use it just as you would any search engine, and it's powered by Yahoo, so you get great results.
Just 500 people searching four times a day will raise about $7300 a year. The Children's Tumor Foundation earned more than $100 last month, money which will go toward improving the health and well being of individuals and families affected by the neurofibromatoses.
