I've been spending some time now trying to find what is a good career path for a web developer but I can't so I hope that others can help me out with this. My latest projects have been developing the front-end of single page web applications. I'm hearing a lot about mobile but I don't know where to even start. It is important to know what the right thing is to invest time into learning. I can't find answers to things like should I learn how to make iphone apps, android apps, responsive apps for smart phones, for tablets...basically, I really want to learn what the trends are.
