As you may have noticed we've launched an all-new, all-awesome commenting system. I should start by saying this is just the beginning and we'll be adding many features to the new system in the weeks and months to come, but for right now there are three highlight — new design that matches our new header, up/down-voting so you can support the really insightful, productive comments. (And, you know, bury other kind...), and report a comment so you can flag spam and anything truly inappropriate.
This is all part of a larger redesign that started with our new header last month and is going to keep rolling out this fall. In the meantime, try out the new comments and let me know what you think of them!
