Coin sentiment analysis - looking for feedback

[titus]

I've been working on a little app to monitor the twitter stream for tweets about a few coins, analyze the sentiment, and plot it on a graph over time. I've found it's best to get feedback early and often. If you have any, please let me know.

what tool are you using for sentiment analysis?

For now, just a node.js module called "sentiment". It just counts up positive and negative words. However, I'm stashing everything in S3 and mongo db, so I can go back and re-score everything once I implement a less naive approach.
