Yeah, I think it's a matter of how you view a story. I accept that reading spoilers first doesn't work for a lot of people and sometimes I don't want things spoiled so I will avoid spoilers. Usually at that point, I just avoid discussion boards until I've seen whatever.
It just hasn't happened lately that I come across a story I want to do that with. I've had a lot of disinterest in things that have come out lately. With movies, with anime, it all starts to blend in and look alike and steal from within their respective genres. So a lot of times I'm on the fence about something. If I read the spoilers and come across something good, I'll then go see the movie or whatever and have a good time with it.
I can't deny the goodness of seeing something unexpected and getting a surprise. Such as in Kyo Kara Maoh!, which I even read spoilers on, I somehow missed
so it was a neat WTF moment for me. And when I saw "Pitch Black" at the theater, I saw it cold. I didn't have the slightest inkling what it was about. And then you have that new Jodie Foster pic where no amount of spoiling would've made it more watchable or any less cliched. What I'm trying to say is that for me it's not so defeatest as "they'll spoil me anyway" and more like screening something to see if it's worth my time to begin with. And I stand by my point that a genuinely good story can not be ruined with spoilers. Many people already had read Lord of Rings. It don't think it really hampered the enjoyment for any of them.
