I have my gripes with SO but I can't imagine a day without it. The number of views on trivial questions says that finding an answer on SO is easier than the way we document code. If there's supplementary documentation done in a Q&A or FAQ fashion, with the right tweaks to rank up in Google, people would not use SO to ask things like ' how to iterate through a list'.
