|Is it really worth a halo?|
As I understand it, Goodsearch runs through Yahoo and it gives a penny per search to the charity of your choice. Elsewhere on the site they note half the revenue goes to the charity of your choice. I can't swear to you that it is legit, although it has been profiled on major TV networks. Once you're set up, you can change your default search engine in your browser (on mine, to the right of the address bar) to Goodsearch.
I'd say the results are fine for about 90% of the things I search. And I'm one of those people who runs a LOT of searches. I signed up about 2 weeks ago and the site says I've earned just over $4.00. Not bad for something that's free to me.
If the search doesn't get me what I need after a couple tries with different words, I just change my search browser to Google and find what I really want. But Goodsearch is a way to give less of your personal data to Google (while giving it to another party, but at least you earn some money in return...probably). Works for me.
