I make no attempt here to log all the mentions of Grameen or even MIFOS (especially since the Nobel prize), but here's one in newsforge: Microfinance and open source: natural partners.
Newsforge is one of the better open source news sites. I mean, no one can match LWN's Weekly Edition for relevance and good writing, but most of the time that I click on a newsforge article, I end up informed. Just to pick another example from today, their article about the reaction to Sun's Java plans is spot-on. It points to some relevant mailing list threads and avoids getting caught up in the hype.
