Yes, many of us do. The problem is many of us do not realize that technically they are not the same. So we wind up have these long arguements about zooms, and depth of field. Technically, what most of us call the motor in our car is really an engine, but that does not cause us to misunderstand how to use our car. The same cannot be said for the confusion over aperture v. f-stop. I did not always understand this, the "AH-HA!" experience came when I finally figured out why my DOF calculations didn't work right, I was using f-stop when I should have be using aperture.
So, what I guess I am saying is, it doesn't hurt to use them interchangably, if you realize that is what you are doing, and don't get confused when it does make a difference.
