Are you taking part in the worldwide social media movement that is #beatcancer? You should be!

Here’s why:

Livestrong wants to beat its own Guinness World Record for “Most Widespread Social Networking Message.” Last year they managed 209,771 unique mentions in 24 hours using the #BeatCancer tag. This year, they want more. You’ve got an hour left! The best part — PayPal and SWAGG will donate $0.05 for every hashtag mention to cancer charities.
