If your goal is to post, then SO is excellent. But if your goal is also to read, there are questions. Nobody ever tried to use Stack Overflow without Google yet. given all its bell and whistles are intended for those who want to post, there are questions yet to answer.
I use SO without Google sometimes, in this way: I search for a phrase or tag, and read the 20 - 30 highest upvoted questions & answers about that — and I learn a lot, sometimes things that I didn't know, that I ought to know.
