I posted a vaguely job related link to a friend on Facebook. She freaked out -- "no work!" "no work!" not on FB!!! There are too many people who could be in big trouble at their jobs because of online comments that can be tracked back to them. I'm not talking about flames or random lies. These are honest comments and reports.

Some forums are OK to identify yourself, but many are dangerous and/or toxic. I'm often considering twice before posting an interesting comment to a forum or site where I don't have the choice to identify myself or not.
