I know who dang is, I just don't see how the phrase living under a rock is offensive? It is a very trivial thing in my culture. Perhaps it is different in America, and I should be more sensitive, but the same goes both ways. To me, that phrase is only lightly ribbing someone who is out of touch with tech...on a tech forum. As I said, in my culture this is not meant as anything offensive and you could be more generous in your interpretation of my meaning. Particularly as I went out of my way to share so many useful links on the subject.
