We had a very productive afternoon mapping the neighborhood in detail with house numbers. End result is here: http://osm.org/go/yy4fNiLdA-

Also shared details with Arjuna on how we can export maps into Wikipedia using svg or with GIS tools.

By evening we had the Kannada Indiranagar streetmap! : http://yogiks.github.io/osm-kn/map/

Would love to do it in other parts of the city if you can organize a venue to meet.
