Thanks for the quick and reasonable reply! I am only a little frustrated that I missed out on so much karma love (I am in my 30's now and find that these things matter less as I get older :), it was more the fact that Medium naturally appends this, so literally all submissions of a Medium article will result in reposts. It's not a simple problem as some URLs will rely on the hash to work correctly, e.g. hxxp://www.example.com/#!/foo/bar, so you can't just strip it. I think it requires some special cases for sites known to do this kind of thing (not sure why Medium do it.) Glad to hear duplicates is an issue you're looking at, has certainly been a problem, though I agree it makes sense to allow it in certain cases. For example I love the XV6 OS and like to see it periodically submitted again from time-to-time to see new discussion. It might even be nice to have an auto-generated list of previous submissions in this case? As an amusing aside, this whole issue has a relationship to the story - perhaps the generated hash uses Math.random() and therefore might actually result in duplicate URLs after not so many resubmissions? ;)
