I feel like being a Ruby developer is like this picture--Hitting a bullseye from a horse doing 30mph.
I really wish we could all agree that Ruby in itself is a beautiful language and that things are "good enough" as they are today. Backwards compatibility needs to be higher on the priority list now that we have many users of Ruby, JRuby, and Rails.
By the way I'm not picking on JRuby here by including them. I'm just trying to be more inclusive since it should be considered/mentioned more. The fact that this is a negative post is in no way reflective of JRuby or meant to pick on them.
