The Long Tail was just released this month. It seems like it has been out forever. The seminal article in Wired appeared almost two years ago. The ideas have been publicized almost daily on Chris Anderson's blog. And yet the book is well worth reading: Gladwell-esque in its energy and clarity, with details that haven't appeared elsewhere. One thing bugs me, though. Let's see the data. We all know what a power-law curve looks like. What we need is to see a power-law curve mapped against the data. Otherwise it's just a theory.
