One of the essential components of the FAQ will be the list of on-topic and off-topic subjects for questions.
Following the model used at this English L&U meta question, let's use this question to vote on what topics should be on and off topic at Apple SE.
In other words, post answers that are of the form:
One subject area you suggest to be considered on-topic
-- or --
One subject area you suggest to be considered off-topic
Then upvote and downvote any answers as you see fit.
