Like someone said here, all that is needed to invalidate some of the claims of this patent is to find some prior art: I am sure that will be doable. so the patent doesn't have much value in the long run.
In the short run, just remember the liberation that Amazon's "one click" patent was: even though it has now been invalidated, it was successfully used in the early days of the patent to destroy Amazon's competition.
If Facebook acts on this patent, I vow to close my account and mount an active anti-FB campaign on all my websites and on on any other public platform: like the all-encompassing email.
