> But, the value of Stack Overflow is that it replaced 10-20 minutes of RTFM with a simple answer.

But at the same time you are learning with blinders on, i.e. you miss out all those things you would have also learned by reading the documentation.

This is not particularly bad when you're just starting out. But if you see RTFM-level questions from people which appear to already be in the business of building complex applications then you start to wonder if this kind of thing incentivizes help-vampirism.

Personally I prefer to answer niche questions or things that are not well-documented yet.
