I dunno, I guess I'm of the mindset that the waves are coming, and you're either on them or under them. These days, I get antsy if I get enough time in one stack that I really feel like I have it cooking. Which is how I've clawed my way up from the embedded programming basement all the way up to javascript now. (Aside: sweet jesus, how do you web guys put up with javascript? It's like java and ml's thalidomide baby.)
