Limit usage of social networking sites to personal use only. Do not write about work issues. Always assume everyone in the world will be able to see what you re writing even if the site limits your post to your friends exclusively. The Internet is an open network through which information typically travels in a readable format. If a normal email message is intercepted on the way to a recipient, its contents can be read quite easily. And, because the Internet is just one large, worldwide network that relies on intermediary computers to direct traffic, many different people may have the opportunity to intercept a message in this way.
