A day into using it, I agree that new Foursquare is a significant improvement in a lot of ways. There’s always been a lot more data than check-ins flowing through Foursquare, but much of it was hidden behind layers of UI. Now those layers have been peeled away.
In addition to these features being hidden in previous versions of the application they were also a lot slower. Now, not only are these features (such as finding interesting places nearby) easier to find, they are really, really snappy. Going to a Google map is no longer an exercise but a pleasure.
