A competent developer should be able to use a tool / language after a few months of learning without having a more or less constant need to rely on third party sources of information like the Internet.

And who's to say that the third party's 'solution' is anywhere near "best practise"????
Also, more and more people seem to think that googling for answers to anything is THE way to do things. Not exactly my idea of either fun or productivity.

I agree, but to listen to many here even 4 or 5 languages is a piece of cake. Somehow I think their idea of "mastery" is being able to write a "Hello world".
