There is a wider implication when people who should know better about safe practices don't apply a little common sense. Claiming "virus" in this case removes personal responsibility.
If someone savvy enough to blog about technology voluntarily exposes their contacts, how will the general public ever be expected to act in a safe manner and thus limit social engineered privacy and security breaches?
