I'm a RoR beginner with a little know-how from other languages like PHP and think you should also include some other interesting parts like Stackoverflow, GitHub, Heroku etc. There is plenty of stuff out there with no real description for a programming-beginner. In my early days I have search for a long time a good description for what a gem is. And this is only one example, lol.
