Two new tweaks for the comments section:
1. The timestamp next to each thread now links to a permalink page with only that thread. This makes referencing specific conversations easier, or you could pass around the link to threads you’ve started and get your friends to reply.
2. The “Most popular” link at top of the comments is a shortcut sending you to a page showing the threads with the largest number of replies. The discussion with the most replies is on top.
