You've seen their status updates as they make their way around town: the social networking trailblazers who use Foursquare to keep the world apprised of their whereabouts. (Bianca's having a cappuccino at Diesel; Ian is catching a show at the Paradise.) What's up with that? Location-based services like Foursquare allow users to send geographic updates to social networks like Facebook or Twitter using their mobile devices -- enabling them to meet up with friends, find worthwhile destinations nearby, make recommendations, and more. These services are enormously popular, and represent a huge growth area in web and mobile development. Want to get in on the action? Thomas Myer's "Introduction to the Foursquare API" provides an overview of location-based services, and shows you how to build your own basic Foursquare app using PHP.
Here's your chance to find out -- and help define -- where it's at. See? Software development is cool (as if there were any doubt).
Until next week,
John Swanson and the developerWorks editorial team
