I link to the Hunger Site on the sidebar because it's a very easy way to do something good. You click once a day and advertisers agree to pay for food for hungry people in exchange for advertisement space on the website. Since it started, they've introduced several other tabs you can click on as well, such as Child Health, Literacy, Animal Rescue, and Breast Cancer, the latter providing free mammograms for poor women.
Recently they added a new tab, Veterans, which gives free meals to those who served America in the armed forces. So take a minute and click on all of these sites -- and remember to do it again tomorrow.
