From the HN guidelines:

> Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.

>Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

>When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

>Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative.
