Shameless Plug: Contribute to digital cartography with OpenStreetMap

I've been trying to write an article for for the last year dealing with open source cartography.  I finally got around to finishing the article and it was published yesterday.  I'm not exactly happy with the way it turned out so I'm hoping to do a part two discussing more than just the OpenStreetMap project and perhaps comparing various open source projects to those that are just crowd-sourced.

I appreciate feedback!
