Plus: the new reply icon is a big improvement over the envelope. It looks like a public discussion now.

Minor bug in the highlighting of new comments, though: clicking on any link to a comment (e..g in the recent comments or your inbox) causes you to go to a partial view of the containing post, and it resets the "new" status for the page, meaning you can't then look around for other new comments on that page. The newness should only be reset when you view the page proper, if it can't be reset on a comment-by-comment basis (and I'm assuming it can't.)

(I still think the "parent" and "permalink" icons need improvement, but I don't have any concrete suggestions. Also, it appears that redacted comments show unredacted if they've already been sent to your inbox.)
