Excellent segment with Dennis Crowley, CEO, Foursquare, interviewed by Mathew Ingram, Senior Writer, Gigaom. Dennis showed a cool video clip of a heatmap of checkins happening in and around NYC. Yikes! Sparkly little yellow things all over… (Lord knows I've been doing my part.)
 
The big question from Mathew was, "Will we get to the point when we don't even have to check in — just walk into a place?" Crowley's answer: "That's a good question: what will a Foursquare app look like that doesn't require a checkin?"  So there you have it. You heard it here first. Or didn't.
