So this is a neat project for you Ruby on Rails learners…. Reddit on Rails is an exercise to use your knowledge of Rails to replicate the functionality of reddit.com.
By now you have the knowledge to accomplish much with Rails. We will use that knowledge to build a website from scratch similar in functionality to http://reddit.com.
Learning a new programming language or system generally go faster if you have a specific goal in mind, and (in general) a typical “hello world” works great, until you decide you need user logins and permissions and suddenly things get a lot harder. This helps that a lot.
