Usually it can go whereever, considering people are ready to answer the questions either way. I have seen them both places, and when a question has been answered, it is just locking the thread and move on. On a more official basis, questions regarding newbie stuff (how to get an armatar, what AP is, how to fave a game) should go in the Newcomer's section, while questions regarding more specific and less - newbie-ish questions could go either way. Most of the questions going to the S'n'S are about games not working, why a section is there/not there, why games disappear, and other things that can be thought of as glitch-listing or otherwise time and place specific questions.
It is like the people believing that the Tavern is for EVERYTHING, which is why they post stories, games and so forth here, when in fact this section is for stuff that does not fit everywhere else.
Section-confusion is a general problem. Now I wonder why you keep asking these questions...
