foursquare gets its plugs in the NY Observer...
If Foursquare goes the way Crowley hopes it will (that is, if you all join), your everyday activities—from your commute to your grocery-shopping—would unlock what he calls “contextually relevant information”: tips, tricks and thoughts sourced directly from people you know. It would “make people more aware of the cities they live in,” and “motivate you to do things you wouldn’t normally do,” Crowley said. If Foursquare succeeds—if it’s adopted by enough people—it would fundamentally change the way many people interact with the city. It might well make today’s guidebooks, weekly event listings, and reviews look like the early versions of Mapquest by comparison.

Not sure where the “nerds” part came from, but John Fischer manages to sum up foursquare better than we seem to do in our pitches. :)
