NY TIMES - Nov 3 - The idea of meeting someone through a mobile app may seem like a risky proposition. But the operators of these services say they are aware of the potential pitfalls and allow users to control how much information they divulge. Some of the apps are stand-alone, while others are new features of established dating sites; including Blendr, OkCupid Locals and HowAboutWe. OkCupid Locals is part of OkCupid, a larger dating site, which says a tenth of its 2.5M active members use the location features in the mobile app. HowAboutWe began a little over a year ago as a site where people post suggestions for dates they would like to have.The trailblazer among these services is Grindr, which is geared toward gay men and has signed up 2.6M members. In late summer its creators released Blendr, aimed at a broader audience.
