I was speaking partially from my experience and, as another poster put it, IDEs help considerably in areas of syntax usage. Besides, with more stable languages (C++ has a 3 yr standardization cadence and new features are not covered well on SO) you can find in-depth answers on SO. Otherwise, many mailing lists (yes, they still exist) are a better source of more current and more detailed treatment of the topic than, "hey, how do I do X so that I can move on to my next thing at work." Don't get me wrong, I love SO, but I feel it's more about, "how do I solve this problem now?" vs "I want to learn more about this topic." It's real value is in the comments that others contribute "around" the accepted answers.
