This Twitter clone is built in Ruby on Rails and attempts to use rails best practices. The application has similar features to Twitter where a user has the ability to: signup, login/logout, post/delete tweets, follow other users, create a profile page, and look at news feed with relevant tweets.
This was developed using the sample application for Ruby on Rails Tutorial: Learn Rails by Example by Michael Hartl.
