I really wanted to use javascript (client and server) for my new webapp. But alas, the various server-side frameworks aren't quite ready for me yet. I think a pure client js + app server js + js db would be fantastic. Even though the various javascript server libs/frameworks are maturing very fast, I cannot afford to toss perfectly good high level solutions that exist with something like merb: production server process management, integrated release scripts, session management and authentication, etc... If you go with js server side at the moment, you get to roll your own for all this. I want this to be the answer, but for right now, I can't afford to cut my teeth on it.
