I recently moved into a full stack developer role. Not because I am a rock star ninja coder, but because I am the only developer employee in the entire company. The only difference now from some of my more specialist dev roles is that I spend a lot more time researching things on Google/Stackoverflow etc. So when I hear full stack developer I can help but thinking "So you spend a lot of time on Google as well?" :)

No, I don't. It is certainly possible to become competent web developer over whole stack as long as you don't expect to be proficient in every currently popular framework out there.

Pick a set of tools, learn them well and move laterally/dive deeper when you need to.
