The article has map samples for comparison at the bottom. I made one for OpenStreetMap, and tried my best to make it a fair comparison.

- Approximately the same zoom level, judged by distance between cities and size of land masses.

- 387x387 pixels (same as images in article)

- Map of approximately the same location

Here is a second image, zoomed-in by one notch. The level of detail provided is more comparable, but arguably I shouldn't have to zoom in to get this. http://img64.imageshack.us/img64/5959/screenshot20100501at92...
