If we write for our peers, and you are a highly qualified academic, then your market is small. But if you just want to get the job done, you have many peers, and your market is enormous. And, at times, every one of us just wants to get the job done; and at times, each of us is so distracted or tired that our effective intelligence drops.

For market success, the ideal place to be is just smart enough to be able to understand the ivory tower issues that the solution needs; but dumb enough to relate to the everyman and agree with him ("Or walk with kings - nor lose the common touch"). Or perhaps it's idealistic vs. pragmatic - regardless, you need both.
