From the point of view of person who uses SO just to find solution, incorrect answers are the biggest problem. It seems that "you don't know what you don't know" does not compute with many people involved in answering SO. But that kinda make sense: at the beginning, SO was great because answers for noob questions where hard to find. At this point, there are so many other resources to get these noob questions answered or they are already answered. Now, people start asking hard stuff - but engineers (I intentionally do not say developers) who know answers on these questions are not interested in answering.
