Thanks to there being so many overlapping modes of communication, it's easy to mix up your private conversations with the announcements you're blasting out to anyone with an internet hookup. Considering how much private information people intentionally volunteer on Facebook and elsewhere, it's now all that much more exciting when you discover those few remaining tidbits of info your friends actually didn't intend to share. We love these Facebook slip-ups because they are a refreshing reminder that people are still capable of being embarrassed by stuff.
