Check-in App Marketing

Users can help market your apps.

The concept is simple: What if you could "check-in" to an app like you do to a physical location with Foursquare? That's the idea behind this SDK from AppBoy. Maybe it will go some way towards helping users find apps they like among hundreds of thousands of choices.

Of course, this depends on the idea getting some traction, and ultimately your app has to get some traffic before the viral marketing really kicks in. There's still no magic bullet... but I welcome attempts to craft one.
