This is a great piece by Sam Ro of Yahoo. It points out clearly the biases that occur with non-GAAP earnings. I would consider it an important educational piece for those not versed in the "game of earnings".
Kopin Tan does a great job sizing up the pluses and minuses of the active/passive debate. While business schools always teach that you don't want to just compete on price, I disagree with them to some degree on this point.
