This will provide even more fuel for Facebook's face recognition technology, which I believe will one day be Facebook's most valuable product, eventually marketed in sometimes disturbing (and secret) ways. As a fellow nonuser of Facebook, it bothers me a bit that I don't even have to participate for them to develop an accurate facial recognition profile of me; my friends, family and colleagues will gladly do it for them.
