I really don't understand this Twitter thing, but they're giving me ten points for pressing a button. How hard can that be? Go here, sign in, scroll down, click a face and enter your Twitter stuff. Boom! You're 10 points richer.
Note: Even if you don't have a Twitter account, try it anyway. I got a pop-up box in the background telling me I would get 10 points within 48 hours even before entering my Twitter info.
