This new downtown eatery has harnessed the power of Facebook for good. Or, more precisely, for delicious: Every so often, the folks at Hub have an online contest to choose a new ice cream flavor. The staff chooses some possibilities, posts them on Facebook, and lets the voting begin. The flavor with the most "likes" becomes a reality. The results are flavors that are already fan-approved, and restaurant-goers are always salivating in anticipation of the new flavor.
