Foursquare CEO Dennis Crowley never wanted his app to be just a “check-in button.” In order to be more than a novelty, Crowley realized Foursquare couldn’t just be about saying “I am here.” And after a rocky couple of years, the company needed to create some momentum, to make their app about social interactions, planning, and discovery—not “I am here” but “let’s go there.” The solution to Foursquare’s solipsistic woes seems to be Swarm, a new location-based social app that launched today.
