SocialRadar is a new mobile application that could become a cool way to find nearby friends and discover other interesting people living or working in the same neighborhood. Or it could just end up being another creepy example of how digital devices are making it easier for our whereabouts to be tracked by just about anyone, including strangers.
Here's how SocialRadar works: After receiving permission to tap into your existing connections on Facebook and other online networks, the app plots the locations of friends and family members, as well as SocialRadar users you don't know. You can choose how far you want Social Radar to look, from several hundred feet to around the whole world.
Sometimes, SocialRadar identifies the locations of friends and family based on geographic information posted on a social network, such as a check-in from a San Francisco bar. Those friends and relatives don't have to be SocialRadar users.
More often, SocialRadar simply keeps tabs on other Social Radar users based on their iPhone's location, as long as their privacy settings allow the surveillance. This means SocialRadar users also will see the locations of complete strangers who also have installed the app.
It's still too early to conclude whether SocialRadar will emerge as a friendship magnet or a stalker's best friend. So far, the iPhone app has been downloaded by fewer than 100,000 users since its release in late January. Other versions of SocialRadar are in the works, including an app tailored for Google Glass, an Internet-connected headset that perches a thumbnail-sized display screen above the user's right eye. Besides Facebook, SocialRadar also pulls information from Twitter, Foursquare, Instagram, LinkedIn and Google Plus.
SocialRadar is run by Michael Chasen, who founded education software maker Blackboard and sold the company for $1.6 billion in 2011 to Providence Equity Partners. So far, Chasen has raised nearly $13 million from venture capitalists and other early investors backing SocialRadar's attempt to make it easier to set up lunch or an impromptu meeting with a friend who just happens to be a few blocks away.
