Never fear, ExcellBook is here!
As you can see, some horrible person (Or people, rather: the clothing company Diesel, has something to do with this atrocity) has taken great pains to create an application that will disguise your Facebook account as an Excel spreadsheet.
Once the application is installed (PC and Mac versions available) open it up and log in through the file menu. Then you’ll be able to see and post status updates and use facebook chat.
Exciting, right?
Your guess is as good as ours as to how exactly this works, but it sure is ridiculous. Check it out at the aptly titled, Be Stupid At Work.
