Good post. Having just started reading Duncan Watt's "Everything is Obvious" (http://amzn.com/0385531680) critique on common sense, this looks like exactly what he's talking about... people who aren't familiar with the difference between the cultures (like me) don't even realize there is a distinction, and hence won't realize that there's even a problem. Even if the problem isn't that big, as some of the comments on the blog suggest, it's still good to know that the distinction exists.
