I've been impressed by the comment policy at Paul Krugman's blog, so I'm going to borrow it here, with a few tweaks:
- No spam
- No comments irrelevant to the post or ongoing comment discussion
- No ad hominem or obscenities
- First time you comment, it's held until I can approve it.
- No comments that stretch beyond roughly a screen
- No consecutive comments to get around the item above
I reserve the right to delete without notice any comment that violates the above.
