It's undeniable that their main developer Q&A site is a really great thing that saved me many hours of work. However, it was somewhat hostile to its more export users from the very beginning: the reputation system favors quickfire replies to grab the first upvotes, and they seem to put a strong emphasis on "cookbook" answers where many of the more nuanced discussions were closed as "opinion based". I think there are some missed opportunities here to make the Q&A site even more useful.<p>However, perhaps that wasn't their focus. My impression is the Q&A site was supposed to be mostly a gateway to their other services, and for that to work, the Q&A part simply had to be "good enough". It's an interesting strategy that perhaps didn't work out quite the way they had hoped it would.
