I really like the concepts behind Crystal. Building a Rails like framework on top of it might get super interesting. I trust thoughtbot in this area as they are thought leaders when it comes to the Rails way of developing webapps. Of course these are just the beginnings and Crystal could still use some batteries in it's core libraries.
