Interesting that you mentioned Foursquare. I considered them a has been for such a long time and only recently realized that they are still around being the geolocation API provider for a bunch of products. Successful pivot, I think.

My assumption was that it was never really a pivot. It seemed that the geolocation API was always their primary strategy. I thought that was why it continues to be odd that so much of Foursquare's usage and network loss seems attributable to their own consumer confusing actions to split out the social network part into a new brand (Swarm) instead of the other way around.
