While I didn't work directly on this project, I do work at Grameen Foundation on the open source maternal health system mentioned at the end of the article. (https://code.google.com/p/motech/ and http://www.motechsuite.org/)

I think it is an interesting story about unintended outcomes, the need to experiment, measure and stop when things aren't proceeding as expected. I'd also personally like to see and hear more on hacker news about the use of technology and open source in the non-profit sector so I figured I'd post an article.
