Idea People

I will never understand "idea people". Mainly because it seems to me that "idea people" often don't really have many ideas that translate to any kind of reality. They are, and I'm genrealizing here, very good at taking about things that are what I would consider common sense and then billing those things as "visionary" or "innovative". Or saying something like this: "We are a good organization because of XXXX. We have made some mistakes, but our core values of XXXX are great. But we need to transform (because someone told us to). So we will transform so that we are XXXX." How is that a transformation? And how many highly-paid think tank type people did it take to come up with this "visionary" plan?
