Flamingo makes it easy to wade through the Twitter Streaming API by handling all connectivity and resource management for you. You just tell it what to track and consume the information in a resque queue. Flamingo isn't a traditional ruby gem. You don't require it into your code. Instead, it's designed to run as a daemon like redis or mysql. It provides a REST interface to change the parameters sent to the Twitter Streaming resource.
