Been getting knee deep in the Javascript frameworks and boilerplates as of late. Kraken KeystoneJS SkelJS Other than these, I'm still on the learning path with .Net, MVC5, and Razor. My only concern is as I get more comfy with MVC and .Net, I'm finding doing front-end development on the Microsoft stack increasingly easier. I'm sort of conflicted in my learning. Should I keep learning .Net, or stick with "the cool kids" and keep looking for newer, faster, better ways of building sites and apps using some of these new fangled JS frameworks?
