SO is a great resource but it's about as good a place to learn something as Wikipedia is to do serious research.

Questions from learners are often poorly formulated and then poorly answered. Since many people are just looking for getting their code to run or finishing their homework, this sort of stuff just piles up without getting fixed.

If you're trying to learn anything non-trivial, don't rely on SO alone.

SO launched a new feature recently called Documentation. Check out the C++ section [1]. Personally, I'm enjoying it a lot. I think they managed to find a very concise way of showing the basic grips of a language and some advanced ones. Most stuff are through examples, which I think works better when you're already familiar with the language, and just wants to do some specific thing. From time to time, I find myself on the page surfing through the C++ topics.
