Maybe you are right. Recently I've been playing with Node and some of my recent projects (they are on http://github.com/carlosedp ) are made with Node.
Also, every time I think about learning Rails deeper I think "damn, I already know how to do this on Node. Why bother..." but the industry wants Rails experience and every Rails developer I read loves it.
That's where the question came. Should I go with the current market or should I invest in a "promise" for the future?
