fair Game on Facebook

A co-worker, Jessica, asks to add you as a friend on Facebook. You accept the request. Since you now have access to Jessica’s Facebook page, you can see things such as her political views, affiliations, her list of likes, the groups she is a fan of, and after-hours photos of her that some may think are inappropriate.

Ethically speaking, is it acceptable to talk to other co-workers, or even Jessica’s supervisor, about things you learned about Jessica from Facebook?

Is this information fair game since it is posted online, and Jessica shared it with you willingly as her online friend or should you keep this information confidential as would probably do if you learned it during a one-on-one conversation over coffee?
