As others have recently commented on the 'statute of limitations' on spoilers, I am wondering whether we are overusing the spoiler markup period. It strikes me that the spoiler markup is somewhat irritating as you are reading and/or responding to a question.
It seems to me, as long as the subject is not a spoiler of a recent movie, then everything else is fair game - i.e. no need for spoiler markup in questions or answers at all. If you read a question about a movie that you have not yet seen - then it is your fault.
What do people think?
