I'm not so sure about that one.
Well, let me rephrase that: DIC has better answers if you're wondering about something more abstractly related to programming, while I would generally go to StackOverflow if I want a quick answer on why the fuck jQuery isn't working properly. Ya know? Most of the time the most praised StackOverflow questions are very basic but extremely common issues, whereas the most praised DIC topics warrant lots of discussion.
Since generally speaking jQuery is working properly, it's just that you or I are not writing the right thing, DIC is again a much more useful resource. Generally, the problem is usually "what don't I understand about this?" and not "why is this not working right?"
So people interested in helping you understand why the fix works are much more useful than the ones who just tell you what the fix is.
