I'd be a lot more sympathetic to all the outcry from outside the U.S. about spoiler space if it weren't for the Euro's (I use that as shorthand for areas other than the U.S.; of course, Europe is only one such area) dirty little secret: uk.media.tv.friends (UMTF). There seems to be a concerted effort to keep UMTF hidden from the U.S. -- for instance, I've seen dicta on UMTF about not crossposting from UMTF to ATF.
Let's face it: the name of *this* group is alt.tv.friends, not "alt.tv.friends.nospoilers" or "alt.tv.friends.no-US-discussion." It should be open to *any* discussion about Friends. Why should U.S. viewers -- or anybody else -- be limited in what they can say, or how they say it, just because the BBC or whomever is a year or two behind? As has been pointed out before, no such consideration is extended to U.S. or other non-U.K. viewers in discussion groups about BBC shows.
So: those want to maintain spoiler space, do it on UMTF; ATF posters can simply refrain from crossposting spoilers to UMTF. Seems simple and fair enough. Or, hey, create "alt.tv.friends.nospoilers," maybe as a group moderated by one of the hardcore no-spoiler types.
