To clarify, my concern is much more about the privacy aspect than the security one. I agree that there's technically not much threat in giving up your first name. From a security standpoint, it doesn't really expose much more threat surface than what already existed. I'm more talking about the general creepiness factor; the expectation of public privacy. This is more subjective, but I think there's a logic to it that is worth questioning.
