The sad thing is, even though Acti-Blizz is supposedly emulating Facebook, even Facebook's privacy options are far better than RealID. Acti-Blizz is not making any of this optional, and as I said to lassiter above, I think they will likely spring on us, one day, quietly, a new TOS that gives consent to have our names shared with other players and "trusted business partners" (with personally-tailored special offers of course). Anyone who waits for it to get to that point will find themselves staring at the screen having to make a split-second choice of whether to keep playing or not.
