The most in demand web technologies of 2015? [on hold]

I apologize if this is not the right place to ask this question. I don't know if the right place does exist. Please recommend a place if you know.

I constantly feel like i want to learn the most beneficial technologies and due the extremely fast growth of technology it is hard to keep up. New frameworks are being released all of the time and some companies get on board and others don't.

What are the most beneficial technologies for a .net web developer to be learning in 2015. whether it be design patterns,data access etc.

Examples: Linq, Entity Framework, MVC design pattern, Web forms :)! lol

Edit: My fears of being bashed over this question due to the fact it can be opinionated etc. What is the best place to ask this question on the internet.
