Why is there an otherwise helpful response to this that is already downvoted to [dead]?

edit: It's back now, but I notice this happening a lot more than it used to. folks, for pete's sake if you find something inaccurate or unsupported in a post that causes you to want it gone, at least support your point with a comment for folks like me. Clueless people like myself end up wondering what the hell I just walked in on when it's dead comment after dead comment that otherwise seem like rational points in an interesting discussion.
