Somewhat tangential, but I wish there were more comprehensive learning resources for Clojure, particularly getting started with web development. Given that there is no equivalent of Django or Rails, and web development in clj is really about assembling a collection of libraries (Ring, Compojure/Moustache, Enlive/Hiccup etc), it is much harder for the initiate to understand how everything fits together. The fact that Rails is so opinionated also really helps the new developer become productive in a relatively short timeframe.<p>I'd imagine this would apply to just about any other language as well really. The Ruby community really is fortunate to have such brilliant free resources out there for learning Rails and the language.
