So far there is 3 ways to get in the beta that I know..
1. Be on Facebook pretty much all day without even blinking.(I hate Facebook with Passion)
2.Be on twitter without breathing and make sure to hit refresh every second. (Twitter have delay problems with tweets)
3.Do not contribute anything to the Forums and have a low post count and also make sure you register your account in 2012.
(This one is my favorite)
by the way I do not have the beta...........
