Social Analytics on MongoDB, Patrick Stokes of Buddy Media does a highly entertaining presentation on MongoDB and its adoption by Buddy Media.
Unfortunately the slides don’t display during the presentation.
Still, refreshing in the honesty about the development process.
PS: I have written to ask about where to find the slides.
Update
You can find the slides at: http://www.slideshare.net/pstokes2/social-analytics-with-mongodb
