Holy crap - how did I miss that!?

That positive-to-negative ratio is about the average that I'm getting, which is comforting.  I'm hoping that the fluctuations in my results will be significant.

Either way though, the search for bitcoin returns ~300 hits, while I'm classifying a few times that amount per hour.  That number will increase as I add more places for the program to search.  My sentiment classifiers are also trained on the specific type of information that they'll be reading, e.g. tweets.
