Twitter will help Foursquare in its quest to become "the location layer of the Internet."
It seems like yesterday that Foursquare was all the rage at South By Southwest. But six years after the social-location app's hyped debut, it seemed like everyone in Austin last week was too busy Meerkating to even think about tapping a check-in button. That's okay, because if Foursquare has a future, it's going to look very different from the vision the company launched with in 2009.
