Lots of people wrestle with the question of what in their lives is public or private, particularly as they put more of them online. But it may pay to err on the side of caution, as plenty of instances continue to pop up to remind us that really, very little, if anything is private once it's online. Take the case of a Philadelphia Eagles stadium worker, apparently fired after he called the team "retarded"
in a status update, for letting a player sign with another team. Or the New York City cop, whose update that he was watching the movie Training Day -- which features Denzel Washington as a cop who doesn't play by the rules -- in order "to brush up on proper police procedure" helped a suspect beat a gun-possession charge
. Part of the issue is that as people get more and more friends online, even stuff they think is private essentially becomes public
. That will undoubtedly have an effect on people's online behavior, and could hamper the growth of social networking and online life-sharing.
