The value of a FAQ is that it stays on top, while the archives get buried.  Keep in mind that we have the same discussions over and over because new people come on board.  Just because an argument was "resolved" in the past does not mean that a new person would see it as resolved now.  People also change their minds or learn new stuff.  For example, I suspect that we will never fully resolve AA's spirituality vs. religiosity or the disease concept of alcoholism no matter how many times we discuss them.  But that's OK, Wikipedia articles are always chsnging which is why it is different.
