Query: a revolution business can manage

yeah, revolutionary language and a new look for a trusted strategy guru. Hamel captures the revolutionary vibe in a better-looking-than-most business book, but stops one step short of being truly revolutionary. This is just enough revolution to keep the current leaders in business, but for the same dare-to-be-different vibe made genuinely radical and personal check out books like Funky Business (another great looking book) and Cluetrain Manifesto. Closer to the imagination generation.
