Editing OSM Boundaries

It's OSM best practice to have boundary=administrative on the constituent ways of a boundary relation, even if the same information is on the country's boundary relation. See http://wiki.openstreetmap.org/wiki/Boundaries and http://wiki.openstreetmap.org/wiki/Relation:boundary
However, the OSM default style only renders borders from relations, so a lot of OSM contributors don't know that the tags on the ways are missing.
Admin_level 2 boundaries on relations (probably no gaps) http://overpass-turbo.eu/s/hcO
Admin_level 2 boundaries on ways (zoom in and look for gaps) http://overpass-turbo.eu/s/hcN

Editing the Rann of Kutch

Q: What is the Rann of Kutch, and why do we care about it on OpenStreetMap?

A: Some context: What's up with the Rann of Kutch? Sample edits/areas: #1 #2

How did it get this way?

Zoomable raster world map (which happens to be using Stamen's Map Stack).

Apparently I broke it by trying a projection other than the original. :(

Based off Calvin Metcalf's version, which in turn is based off Jason Davies map which is a combination of Mike Bostock’s raster reprojection, automatic projection tiles and a MapBox terrain example.

Thanks to Mike Bostock and Nelson Minar for their comments and encouragement! And Obviously Jason Davies for making the original.

Color ramps: *-fill

Basic usage

marker-fill: ramp([column_name], colorbrewer(Greens));
