The goal of this project is to practice consuming web service APIs as well as publishing an API of your own. You will create a Tumblr or Friendfeed-like system that lets users publish a timeline of activities that they have either created on the site or that are activity imported from another third-party site such as GitHub, Twitter, and Instagram. In addition, you will provide an API for reading and writing to a user’s activity stream, and publish a gem to let other application developers consume your API.
