this is cool, but you can do the same with beautifulsoup and textblob in far fewer lines of code and you wouldn't need any web services. if textblob isn't your thing there's plenty of svm implementations out there.
for more interesting sentiment analysis approaches check out sentence vectors, that's the current bleeding edge of research in this area.
most sentiment analysis systems need to use an ensemble classifier because the domain of the text is very important. identifying the domain and using the appropriate domain specific model is important.
