Trying Bing can help someone in school.
Google has become the standard search engine of choice around the world, but it's not the only one in the game. Microsoft's Bing is a fine alternative, but getting people to switch is hard. Would you switch your search engine if Microsoft were to donate $3 to schools in need?
Microsoft has created Search With Purpose, a page that will add Bing as a search provider in Firefox and IE (though the whole donation process will work with Chrome and Safari too) and send you a $3 donation code for you to enter in yourself.
The page notes "Bing will donate up to $100,000 in $3 donation codes during the promotion. Donation codes may only be used at DonorsChoose.org and expire on August 31, 2010." Nevertheless, it's to a good cause and you don't really have to be committed to Bing if you find Google is still a better fit for your internet needs.
