Seth Godin has an interesting take on higher ed, and references the DIY U book I mentioned in a presentation at our campus's main IT meeting a couple of weeks ago. See "The coming melt-down in higher education (as seen by a marketer)".
The always interesting Michael Feldstein also has a take on DIY U.
Godin mentions Deep Springs College, across the Sierra from us. I've never felt the need for a formal mentor, but the guy I learned the most about higher education was a Deep Springs alumnus and president, Brandt Kehoe (quoted in this article from 1985).
Speaking of the Sierra, having gotten giardia on a backbacking trip to Blaney Meadows, I found "Livestock waste is polluting the Sierra's water" interesting.
