The 'new' page scrolls by so fast that it is pretty hard to keep track of all the links submitted.
That would go a long way towards getting rid of some of the frustration experienced by the 'old hands' here.
Maybe introduce categories, say 'real hacker news' and 'the rest' to begin with ?
Another easy to add feature would be something that checks the intersection between the vocabulary of the 'new' submission with the last 100 or so older submissions, above a certain threshold there could be a 'your submission is similar to 'x' message, are you sure you want to submit' confirmation.
Compliments to RiderOfGiraffes for spotting all those dupes btw!
well, in this instance you could upvote the dupe in the hopes that more people will see it on the front page. on a slightly related note, i've noticed these days that the posts with higher numbers of votes depend not only on the quality of the content, but also the reputation of the submitter.
