Unofficial HN community guide: Short comments meant to be viewed as sarcasm end up being interpreted incorrectly often when used in a serious forum. A short clarifying rider sentence explaining your real opinion often helps. That may ruin the joke, but if your comment was just to make a joke, it probably wasn't strong enough reason to comment anyway (for additional info on jokes, see the section entitled How to make a joke and not get downvoted).

Addendum: Poe's law is alive and well.

(The above is of course my take, and other people will follow their own best practices)
