Articles like these over generalize, and I hope that anyone who reads this article doesn't assume everything they read is gospel.
I know my point of view on MBA's isn't the popular one on HN, and that's fine.. but an MBA was just right for my career, and it is for some others as well.
As for "...MBAs brandishing spreadsheets, the latest two-by-twos and the guilt induced by some watery ethics course." Way to read the "10 day MBA" and write an article about it. Oh wait a minute, the author is also basically pushing his own book on basically the same subject.
