It would depend on which job market you are trying to target, this is my guess (it also differs based on geography) Enterprises (mostly in this order) - Java (standard J2ee framework) - Javascript, HTML, CSS - .net (mostly asp.net, many corporate sites are built with this) - specific applications like Oracle, SAP etc. Startups - Javascript, HTML, CSS (and any popular framework) - beyond this there is no one thing, it is mostly the founders comfort zone Software Biggies - their software stack - Javascript, HTML, CSS (ans any popular framework) But given your profile and the nature of posts that you have made, I am curious why you raised this question?
