I gave up on Foursquare a few months ago, but decided to bring it back for the trip. I’m surprised that Foursquare does not have a feature to map out a series of stops and so far my investigation into 3rd party developers has not found anything useful.
As indicated by the infographic, when it came down to finding things and getting around in the city, Google dominated the city/company focused apps. The information was more complete and easier to get to through Google Places or search. Long live Google!
