OK, just curious: how is the posting of judgemental one-liners unrelated to the subject at hand somehow less of an etiquette violation than a perfectly harmless (yet responsive and topical) rhetorical snipe? I mean, as flames go this was pretty mild sauce. Can't you spend your time policing some of the legitimate flame wars that pop up here instead?
Not cool. At all. (I don't know enough security to determine if you are correct or not, so my comment only applies to your tone)
