StumbleUpon is a new website where you can "stumble upon" web content that fits your personality. kind of like Pinterest. Right now they are doing a promotion where if you refer 5 friends to sign up for free, you get a $10 amazon card.
I just signed up, and it was super easy. You just sign up, then you click a few things that interest you and that's it! You can refer people through facebook, email, or your own link.
Here's how to do it.
1. Sign up for StumbleUpon Here
2. Then head HERE for your referral link and to refer friends.
3. You then can share via facebook, link, twitter, or email!
Who doesn't want free money! Especially with Christmas coming up!
