Title: Today we&#x27;d like to introduce five new features and one moderator.<p>1. You can collapse comments in threads. If you&#x27;re logged in, collapses persist across page refreshes and devices for a week.<p>2. You can tell which way you voted and undo a vote if you want. An &#x27;unvote&#x27; or &#x27;undown&#x27; link appears after a post&#x27;s timestamp when you vote.<p>3. Save and share the best stories and comments. Click on a post&#x27;s timestamp to go to its page, then click &#x27;favorite&#x27; at the top. Your favorites are linked from your profile, and you can browse other users&#x27; from theirs.<p>4. On the front page and &#x2F;newest, click &#x27;hide&#x27; if you no longer want to see a story. The next story in the list will slide up at the bottom. If you change your mind, visit &#x2F;hidden and click &#x27;unhide&#x27;. If you&#x27;re logged in, hidden stories persist for a week.<p>5. Find out which stories were the most popular on HN on a given day by visiting &#x2F;front?day=yyyy-mm-dd. You&#x27;ll see all the front page stories for that day, sorted by how much time they spent there. For example, Alan Kay&#x27;s AMA had the most front page time on June 20: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;front?day=2016-06-20.<p>Finally, I&#x27;m pleased to introduce sctb, a.k.a. Scott Bell, as a Hacker News moderator. Scott has been moderating HN incognito for a long time, but starting today he and I will be sharing the public part of the job. Since Scott is familiar with all aspects of HN moderation, you shouldn&#x27;t notice any changes in practice; this is just an internal refactoring to enable such innovations as vacations and a day off. Scott is my cofounder from Skysheet (YC W09), an excellent programmer with a meticulous eye for detail, and a thoroughly decent human being. Please welcome him and be nice!
