Arduino Facebook Notifier?

[css123]

Hi there,
I'm trying to make an arduino project in which it reads from a certain address where Facebook changes to notify of new posts, likes, etc. I want to make a small lamp to flash every time I get a notification from Facebook. However, I don't have a clue what address Facebook uses to where I could "read" if I've received a new notification and have arduino act accordingly by flashing an LED. I don't have an Ethernet Shield so I'd be communicating through a serial cable. If anybody can walk me through setting this up that'd be great, I couldn't find anything of help elsewhere online. I have a good understanding of arduino but this would be my first networking arduino project.
Thanks in Advance!
