GoodSearch is a search engine, now powered by yahoo that donated profits from advertising revenue to the charity of your choice. GoodSearch has a goal of donating 50% of revenues to charity, however in the fine print there is a caveat about a lower percentage in the first year.
Anyway, seems like a good idea, wish you could choose your own favorite search engine though and not be forced to use Yahoo. This kind of reminds me a bit of the Interra Project where you decide where a percentage of the profits made by your shopping go.
Also is someone relevant to the AttentionTrust discussion we were having. What if you could direct profits from the selling of your attention data to the charities of your choice?
