A survey conducted by Princess Cruises found 32 percent of parents aged over 50 shared their travel photos and experiences with their family and friends through Facebook and only 28 percent still sent postcards. "Before Facebook, tourists would go to the postcard stand and try to find the most magnificent looking card, maybe to make people jealous, but mostly to share their stories. Now they have Facebook and it's exactly the same only these stories are shared instantly." said Jim Macnamara, professor of Public Communication at the University of Technology, Sydney.

Teenagers for fear of being analyzed by their parents are now cautious about what they post on Facebook. Most of them these days choose not to share something because they think it’ll reflect badly on them, something they would not have considered had it not been for their parents’ presence on Facebook these days. Some even go a step further and use fake names even though it violates Facebook’s terms of use.

About $18 million was wiped off Facebook’s market value when the company CFO David Ebersman said Facebook was seeing slightly reduced usage from younger teens. The time for Facebook to reinvent itself so as to encourage folks from all age groups has come.
