Over their history, Foursquare has been an iPhone-first company. The app initially launched on the iPhone back in 2009, and new features have typically rolled out to iPhone first. But with a new feature today, Foursquare has shaken things up, going Android (and web) first. The new feature is a nice one: Notifications . Unlike the push notifications for check-ins you're used to seeing on the Foursquare mobile apps, these new Notifications focus on other activities on Foursquare "beyond the check-in". That means things like comments on check-ins and photos, alerts when friends sign up, alerts about tips, alerts when you're ousted as mayor, swarming alerts, etc.
