All this sounds really “cool” but start off by learning good ol’ PHP and mySQL (I KNOW that is not a programming language!). Then you can consider developing code for the LARGEST framework in the WORLD: WordPress! It is not going away for a looooong time, and there is a much larger market for developers that can program PHP and mySQL than ANY of the above. Since “Day One” there has always been some guys that have a “really neat” alternative programming language but the programming language is not the bottleneck. It’s the capability of the developer to solve problems and the existing tools are more than sufficient to do this. Also, jquery ain’t that bad either!
