OK, even though the comment that you think is too snarky does not bother me, I will take this conversation to mean that I should use a stricter standard than merely "would not bother me" to which to hold my own comments.

The comment at which the snark was direct is a bad comment (the writer does not know enough about astronomy to make any weird feeling he has about an astronomy article to be the least bit informative) but I'll downvote comments like that rather than try to defend snarky replies to them.
