I must comment on this article: Using Facebook as a Resume.
Is there no longer any separation between your personal life and business? There is already a study showing Facebook as a major contributor to divorce. Why, tell me, do I want a company, where I want to work, read posts to my High School or College friends, my family and people I call friends. Giving a company my Facebook password, are you crazy? It's a "Social Network".
Sorry, my life is not an open book. Work performance and accomplishments should rule in the business setting.
This is just another form of employment discrimination. We'll call it SND for Social Network Discrimination.
Here is a great article about this subject from the Wharton School of the University of Pennsylvania
Hold That Password.
