Actually, I watch the content in a timely manner to experience it without having it spoiled by everyone else that watched it over the course of the prior year.
And yes, that happens quite often in my life, unfortunately. Sad part is that it's usually not the same people who do it, which makes it difficult to avoid.
Remember the twist in The Sixth Sense that you didn't see coming? I don't. Someone saw me with the disc in hand and spoiled it before I even put it in my DVD player.
Spoilers aren't bad if you're at the front of the release curve.
