SANS: Facebook “joke” leads to firing:
About: News.com.au: Firing Dispatcher for Facebook drug joke
This is a sign of the times. When social networks and off-of-work comments lead to trouble at work. There is some sage advice from Marcus Ranum (writer of firewalls and legendary IDS products) who said recently "If you don't want to make something public don't blog, facebook, tweet, or otherwise publicly announce it! Three people can keep a secret if two of them are dead and nobody has published it
on the Internet for all their 'friends' to see."
