Why don’t Indians use Strava when they train?

I just discovered Strava's Saturday heatmap
http://www.strava.com/saturday-heatmap
and it was really interesting looking at the major cities that I actually know.
As I navigated over India, Pakistan etc there was nothing – no data showing. I know from reading this forum that there are plenty of sports mad people in those countries and they must train. Do you all use a different tracking system like training peaks or something?
