<3 Thanks for sharing!

I wasn’t aware of how the name was derived. A small village very close to my native place, Thiruvisainallur, is called Edayathumangalam (Not mapped on OpenStreetMap yet). The naming breaks down to Idai (between) - aaru (river - the Kollidam river and another river (one of the many tributaries of the Kaveri) - mangalam (temple) - the temple between the two rivers. The Edayathumangalam temple is probably the most famous landmark there, and gave birth to an entire village that surrounds it now and shares its name. : )

10k features mapped in that context are of a different inherent value than 10k features mapped by a local mapper walking the streets and mapping addresses, trash bins, fire hydrants, addresses and all kinds of other stuff

Totally. The tool right now is completely agnostic to what types of changes it tracks.

long term sustained value of the data for the project

Our premise is that high quality data following best practices collaboratively created with community where possible is welcome. Take a look here for instance how we recently worked on realigning highways in Japan https://github.com/mapbox/mapping/issues/120

Additionally, we have noticed that aligning over satellite imagery is a good first step, and allows mappers on the field to add details more easily. http://www.openstreetmap.org/user/jinalfoflia/diary/36706 http://www.openstreetmap.org/user/Arunasank/diary/36332
