An interesting feature idea would be to allow there to be multiple links for a given article topic, and allow upvoting and downvoting on the particular links, without having to submit new links that are not obviously related to the same story (and do not share comment threads, etc.). This might lead to a little bit of confusion over particular points made in one of the articles, but it would be balanced against the accessibility of other news sources, and would give us a way to organically work free of blog spam.
