I like this a lot.  Bookmarked.

But... while all the math, bots, spiders, & etc. operating behind the scenes appear to work very well, the page itself leaves a bit to be desired.

I'm Firefox 20.0 on Debian.  Can't see the "Price Correlation:" line at all, and I have no way to get to it.  The center box (where all the info is) won't come all the way up to size - there are sliders top and bottom - although it takes up less than 10% of my screen.

Planning an Android app?
