Twitance is a recommendation tool that analyzes tweets and Twitter activity to provide recommendations to help users better engage audiences. It checks responses to tweets like retweets, replies, and favorites to determine influencers. This helps brands and individuals focus their strategies and plan their tweets. The tool will provide two recommendation lists - a universal list and a followers list - as well as reach analytics over time and influential users for a given tweet. It is built using Ruby on Rails, MongoDB, Elastic Search, and the Twitter API.
