I'm going to opt out because I object to these lawyers claiming they're acting on my behalf in suing Google without my consent. I understand that this is considered legally acceptable for class actions in the United States, but I don't think it is reasonable or ethical. You should need explicit authorization to claim to represent any competent adult.

And for what it's worth, I never got my feathers too ruffled by the Buzz thing anyway.

EDIT: And the notice document says you'll need to snail mail all of the following to our intrepid lawyers in order to opt out: "your full name, address, reason why you want out of the Settlement" -- best of all, a nebulous "proof that you used Gmail at some point after February 9, 2010" -- plus "your signature, and the date." What exactly will be accepted as proof? Convenient how they don't bother to tell us. I'm assuming they won't accept OAuth tokens...
