[[User:Ned Scott]]'s written a proposal, currently up at [[Wikipedia:Spoiler warning]] (after much hacking by others) which strikes me as sane and workable.
I note that I've been removing inappropriate spoilers as fast as I can and almost all have stayed that way. Whereas those reverting me have tended to be blocked for 3RR a lot, i.e. are hotheads. This suggests to me that the actual wiki opinion is not so very much in favour of spoilers everywhere. I wonder if we'll start getting email from aggrieved readers, i.e. the people spoilers are supposed to be for.
