I just rolled out a feature that shows you how many new comments a post has since you last looked at it.

1. It’s just plain useful. Everyone likes knowing at a glance if there’s fresh activity.

2. Our front page sorting algorithm is a hybrid of Reddit + 4chan. That means old posts can (and do) bubble back to the top. But if you’ve already clicked into a post once, you’re probably not going to click in again unless you know there is something there. Well now you know.

What I want to do next:

• Highlighting new comments inside the thread itself
• Maybe getting the comments to sort with the same alg as the front page.

Let me know your thoughts, and suggest new features. Appreciated!
