Indeed, Facebook has re-defined the meaning of ‘ social awkwardness’. Much as I admire it for the it-let’s-me-keep-in-touch factor, the charm somewhat wears off as described in the above link: For example, when people feel the need to tell others about their change in relationship status, lest someone complains that they had to find out about it through Facebook.
What a stigma that must be! Take a hint, maybe? :p
