Ruby on Rails

I've spent quite a bit of time playing with this Ruby on Rails thing. It's amazing that I was able to build such a nice basic CRUD app w/ only 57 lines of code. Now, I know this app didn't do much - just manage an Online Cookbook (i.e. the Rolling on Rails tutorial). I'm going to go through "Four Days on Rails" next since it purports to be a tutorial with a "Real App." I'm excited about maybe using Ruby for rapid prototyping for our enterprise-class Java apps...maybe even for production apps. Who knows...Ruby may replace Java? :-)
