Comments.
A reminder: I approve comments manually.
I don't mind vulgarity, wrongness, or even the mild ad-homenim...as long as it contributes to the discussion. Should you post a comment here that does not contribute, expect it to be binned or treated as spam -- without warning. Be witty, be carefree, be data-driven, be on point, but most of all, write something that will try to convince someone else you're right. The elation of asserting something you feel is self-evident is a joy that falls into despair far too quickly and is too easily dashed by argument and evidence.
