I was amazed to find out that they knew about it but they were like "what?! that thing is totally WRONG" or "it's to unstructured to send any clear message" or "is the epitome of BAD DESIGN" etc. And later heard similar thoughts from business people that tried it, like "yeah, that's even worse than keynote" or "couldn't get anything done with that".
So I still wonder: why do lots of business/"creative-business" people find Prezi such a bad idea and some even call it "worse than powerpoint"?! (...to me it seemed like a really big step forward in the presentation world)
