If you are a Facebook user and you want to use Facebook at work without being obvious about it (after all, it is work), there's an add-on for Outlook that integrates Outlook with Facebook. Once it's installed. Using this add-on you can update your Facebook status; see your friend statuses; and see notifications of new friend requests, messages, invites, pokes. And all the while, it looks like you are getting some work done in Outlook.
