We've banned that account—for obvious reasons, given how it behaved in this thread.

Unfortunately, several of your comments were also uncivil. Please err on the side of civility when posting here.

Also, please don't engage in flamewars on HN. A good-faith discussion about how someone is wrong is fine, but at the point when good faith dries up, such discussions become tedious tit-for-tats, which amounts to mutual trolling. We definitely don't want those kinds of threads here.
