Nice implementation, simple and helpful UI (specially "Need help? try these links.")!

A glitch: I entered http://www.megacz.com/berkeley/coq-in-ghc/ and it says 'This link has not been posted to reddit.'

A suggestion: Can you add a URL route to automatically initialize the lookup. Eg. /?url={url} or #{url}. Its handy for sharing.

A question: Which sentiment analysis library are you using. It seems to be classifying the comments on the mentioned link as negative.

Edit: Alright, looks like https://raw.githubusercontent.com/tgallant/blog-checker/mast... is being used to calculate the score.
