Facebook goes purple for Cancer Awareness Day. If anyone was on Facebook yesterday I am sure they noticed at least one of their Facebook friends with a purple profile picture. One by one every UT sorority girl as well as many of the other UT student's profile pictures were turning bright purple. No, this was not just a new cute and fun social networking trend. The purple profile pictures were posted for a good cause. Chevrolet promised to donate $1 to the American Cancer Society for every purple profile picture in support of World Cancer Day. After spending a whole lot of money on a Super Bowl commercial, I applaud Chevy for their generous donation to this very important cause. My Facebook profile picture was purple and I hope yours was too!
