This is generally a good way to learn things, as I learn best by doing. But, when approaching a new language or framework, I need some practical guidance on building applications using that language/framework. Ideally I'm looking for the equivalent of Michael Hartl's Ruby on Rails Tutorial. I'm not a ruby/rails developer, but I did follow his tutorial and it was one of the best guides I've followed (pedagogically speaking).
