Great idea. Have you guys considered adding an overall rating for the sentiment in question. For instance, searching for iphone5s will return the total Positive, Neutral and Negative sentiments.

And what sources do you crawl so far?

Thanks. We have an average rating for the subject in question above the graph. There is also a list of sources crawled below the graph (we are working on expanding this list significantly in the near future).
