That was the first thing I noticed too when I visited OFN 
There are great libraries like Mapbox for Openstreetmaps(OSM) which are gorgeous and at the same time have varied usecases.
Can think of Foursquare etc. as examples which strike which are using it.
The Mapbox team in India, based out of Blr. are friends with me and we are part of the organization called Datameet, so I can try initiating anything, if we want to take it forward.
Cheers.
