I have never been so spoiled on LJ for a show as I have been for Doctor Who. I don't know why that is. It's not the first time I've been watching a show that aired in Canada a week or two behind wherever it aired first. (We were like that with Angel for a while, IIRC.) I don't even belong to any comms for the show -- this is just my flist.
I realise there has to be some statute of limitations for spoilers else we'd all be cut-tagging "Darth Vader is Luke's father", but I don't think a week and half is too much to ask.
And this isn't directed at any one person since there have been four or five that have spoiled me so far. I even took someone off my flist a few weeks ago because of it.
The audience is so much smaller than for most of the things I'm watching. Is that why, maybe? Less of a "fandom" feeling? Or just the assumption that anyone who is watching is either watching live or not reading LJ until they can d/l the file a few hours later?
Whatever the reason: no love.
