You've been posting uncivilly to HN. We ban accounts that do that, so would you please (re-)read the site rules and comment civilly and substantively from now on?
Civilly I can give you, but substantively?
> The test for substance is a lot like it is for links. Does your comment teach us anything?
I don't understand how you can claim I'm not commenting "substantively" when I'm correcting blatantly wrong info with citations.
