To rejoin facebook or not to rejoin, that is the question. Help?!?

Alright, I deactivated my facebook about 7-8 months ago due to some drama that was going on that I just couldn't take. Things have cooled down and my friends want me to come back. Could you please list the Pros and Cons of reactivating my facebook and give your opinion as to whether or not I should reactivate? If the Pros outweigh the Cons, I'll probably reactivate and vice versa. Thank you in advance!!
