I created this Spark Streaming service to analyze hashtags coming out of Twitter. Why? Politics can be entertaining, or irritating, depending on your perception, but discussions about our culture and its people are worth having.
This tool is open source and provides a "top ten" report of Tweets matching any of a given (configurable) set of keywords. Enjoy!
