Do you have a week's worth of vacation days and a place to stay in NYC? Seth Godin is offering a week-long, alternative M.B.A. for free to folks who work for social benefit organizations. He doesn't explicitly include librarians, but I think the case wouldn't be too hard to make. Of course, free is relative in this case; you still have to pay for your own transportation and lodging. And Seth promises lots of hard work and studying. If you feel up to the challenge, go to Seth's blog
and apply for a seat in the course.
