I voted on the fence. Looks like I'm the only one. Story of my life!
I didn't want to vote in the negative outright, because I don't agree with the wording of the "Not on your effing life" option. That wording implies that I'm being precious about revealing my true age. I have no such qualms about doing so.
However, having said that, I agree with the others who have observed that we are already acknowledging birthdays at the foot of the homepage.
So, I guess what I'm trying to say is, if we are already doing it, why do we have to do it twice?
