I don't mind opt-out, as long as I know it's opt-out. The way FB rolls features out is they do it silently in the background, which is sort of grating. I wouldn't mind at all if there was a one-time "Hey, we made this cool new thing, I'm going to turn it on now, but I'm giving you a chance of not using it if you want" message on my next login.
