AwkwardTurtle.com
If you don't have any idea what an "awkward turtle" is, then you may not understand this site. For the millions of other people out there, welcome home. awkwardturtle.com is an original creation by Kungfuters. The concept is simple: post a story about an awkward moment you've experienced, and if enough people vote for you, you win the weekly prize. It's easy. It's fun. It works. So far, the prizes have ranged from t-shirts to CDs to $60 in iTunes, and it's only going to get better as we seek out new sponsors.
When building awkwardturtle.com, we made the assumption that people are tired of making compulsory accounts for every new website they visit. Who wants to keep up with all those usernames and passwords? So, we made access to the site possible solely through existing social networks, currently Facebook and Twitter. Just a couple of clicks connects you, and you're ready to post or vote. The bonus is that you can easily bring all of your friends with you. After all, the more of them that vote for you, the more likely you are to win.
