I huge shout out to my Blast Radius colleagues who created the Facebook app for the Starbucks Pumpkin Spice Latte contest (or PSL as heard around the office). Not only did the contest engage a large portion of the nearly 25 million Starbucks Facebook Fans and create a huge buzz around this seasonal drink, but it was the most shared Mashable story in August.
Hum, is the equally loved eggnog latte next?
