Some grouping or merging of URLs for major news would be nice, though hard to implement. For example Apple releases a new product, new version of Firefox, new S1 filing of $unicorn. Each leads to 10 different stories being submitted in very short time period. Different websites, sometimes just slightly different URLs (bbc.com vs bbc.co.uk or mobile vs desktop URL) or link to a tweet which then links to bbc.com again. Currently we can only flag and point to the submission with the most traction/upvotes/comments, usually the one that made it to the frontpage first. With an Apple event that leads to a race who can post a URL first (sometimes guessing, thus before the URL exists, or before the URL is availble in parts of the world). I've seen the moderators can merge threads, they can also change the URL of a submission if a better source is available. Maybe users could marks stories as "essentially the same as". I quite like reddit's meta threads. A threads like "Apple September event" that stays in top position and is created before the event. But reddit is better with long comment threads (500+ comments) and sorting by time, not votes. I'm sure it would be a major project and lead to more moderation work. Users can hide submissions. Sometimes I wish I could hide users or domains, too.
