After hitting the 3 billion check-in milestone, Foursquare has released “The Best of Foursquare 2012.” The list features the top businesses based on user reviews and number of check-ins. So people don’t get too overwhelmed, the site allows users to search one of 30 city locations. “One of the things our data shows is how each city is unique. Bostonians love seafood, Portland is a veggie paradise, and Philly may be the city of brotherly love, but what they really love is a good sandwich. Since no two cities are the same, each page is customized to help you get a feel for the local flavor,” the blog states. [Source: Foursquare]
