We have a couple of new, cool features for you commenters out there: permalink threads and most popular sorting. How do they work? Well, the timestamp next to each thread in comments (a comment and its responses) is now a link to that thread that stands on its own. You can direct people to that conversation specifically using it. As for popular sorting, you should now see a "Most Popular" link at the top of comment threads. Clicking it brings you to a page showing the threads with the largest number of replies, with the discussion with the most replies on top. Try 'em out and let us know what you think!
