Social discovery service (and TechCrunch Disrupt alumni) Sonar has some big news today, and just in time for SXSW: it’s arriving on Android. According to founder Brett Martin, support for the Android platform has long been users’ most frequent request for the service.

But that’s not the only thing that’s new. Along with the Android launch, the company is also making a slight, but important shift, in terms of how it will show its users recommended people nearby.
