subreddits or filtering are a must, and I don't know what a pubmed score is - is it more technically challenging to handle arbitrary doi.dx URLs? How about support for ArXiv? If the difficulty is gaining ranking for things, then I guess you just need more users and a way to handle upvotes - let me know if you want me to advertise it to all my grad student friends with institution subscriptions inside all these paywalls. You'll have to support physics articles before they'll care, of course...
