Any comment that isn’t part of an active thread, or had a recent response, will be collapsed — unless the commenter is a star or one of your friends. Stars are now only by an editor or admin. Previously, you get earn a star just by having a certain number of friends and followers, but no longer. However, if you already have a star, you will get to keep it. Unless you start stinking and we remove it. You’ve probably already noticed these changes, they’ve been in effect for about a week.
