      Thanks. Although it just occurred to me: I’m pretty sure that was the first time I was viewing that post.

        Confirmed. I just opened a post I’d never opened before, and one comment was highlighted. It had been posted just four minutes earlier, so perhaps it is determined by a time limit.

    They are new comments. If you see any comment which look “more” highlighted (e.g. yellow background) and is pinned to the top of the post, then it is a manually distinguished comment by a moderator.
