> why people still use Java
I am not into Java but I'd rather prefer using Java the next 10 years than Ruby 1 month. At least I get a perfect language implementation (the JVM) with Java.

I don't agree with you about the JVM, but you're clearly ignorant of Ruby if you're not aware that there's a Ruby implementation that runs on the JVM (JRuby).
I'd very much like to learn the next great framework and its language - I just haven't been convinced by any of the front-runners quite yet (especially in terms of ecosystem resources). When that happens, you can bet many coders like me will jump on it. Till then we'll just continue to work on our Rails apps.
