FACEBOOK IS GOING WEIRD!?

Normally on the news feed page, you can see statuses and stuff etc. On the right there usually is events, birthdays and poke etc...but now there is a replicate of the news feed! Is this a virus or something? Or just a one off thing? Why is there a smaller news feed on the side? Chat bars gone too! aswell as the chat icons on the left side! Arghhhh!
