I echo the concerns others have posted regarding FB privacy (or lack thereof) and system wide integration. So, what happens when there is a "bug" that ends up saving/transmitting everything I've been typing, including confidential information...maybe even keychain passwords? I can see that happening...especially the keychain thing since it will undoubtedly save your FB password. I have a FB account, but I know full well how lacking their security is. Accessing it from my iOS device is acceptable to me, but having system wide integration on my Mac Pro that I use for design work? Eh....that makes me uncomfortable.
