Justin Smith, editor of InsideFacebook.com, acknowledged that the non-stop cocktail party with family, friends and mere acquaintances can give rise to awkward moments and embarrassments.
But said, "Most people just joining Facebook now will probably be surprised by the value of the information that people are sharing that they just wouldn't get access to otherwise."
As the rules we live by in our day-to-day interactions migrate to Facebook, he said we'll slowly learn what to share and who to share it with.
"I think as a culture, we still have a learning curve in terms of what's appropriate to share on Facebook and how to negotiate the social contracts that exist between you and all the people that you know," said Smith.
And, if we never learn, there's always Garbo.
