Since I'm a fan of Penn State on Facebook, I saw they are promoting a contest that will earn 10K donated by the Big Ten Network, to the winning school's alumni association. Each school is represented by a bobblehead of a school icon (ours is Cappy).
To be able to vote, you need to do a quick registration (which you can opt to not receive any updates from the BTN in case you were worried about spam). Then you click on the school on the bar on the left (we're at the top since we're currently in 1st place), and then you "tap" the bobblehead up to 10 times per day (and you can do it every day).
Usually these are just popularity polls, and don't do anything other than see who can organize the most people to vote, but this time there's actually a benefit to PSU through the donation of $10,000.
Currently we're in 1st place, but according to their very scientific "Bobble Meter" Purdue, and Drew Brees are close behind.
There's also a separate sweepstakes you can sign up for to be entered for a chance to win one of the B10 bobble heads, or a 3-night vacation to an away football game next fall, in case you're interested.
Cast your "votes" here, and remember you can do it every day, click on the bobblemeter in the lower right-hand corner of the screen to register to vote: http://www.bigtenicons.com/
