Got a Tech Hunch? Use 'Milkshake Test'

(Newser) – Five years ago, everyone was ready for a Second Life revolution—but the virtual world has largely fizzled. Google and iPods, on the other hand, have lived up to the hype. How do we know when to believe in lofty tech expectations? At Slate, Dan and Chip Heath propose a thought experiment adapted from writer Clay Christensen. Pretend marketers learn that milkshakes sell best to early-morning commuters. The commuters are, in effect, hiring those shakes to do a specific job—providing a quick and easy breakfast.
