Good point. Although I didn't stipulate this in my original post I kinda assumed no matter what language I pick I will have to continue increasing my js knowledge to continue building web apps. I already do already use js and jquery often.
That's actually not a bad idea. Server side languages are fundamentally equivalent in the sense that what one can do another can do, though it may be easier or more fun in one language or another. Javascript lets you program the user interface in the browser. Check out http://jquery.com/ for a useful Javascript client-side library.
