I just signed up and was offered to hook up my Facebook account to my Diaspora account. Is this what you mean?
Personally I chose not to; the reason I'm apathetic to Facebook and rarely use it these days is because of the constant privacy breaches and then the NSA news. Why sign up to an anonymous and decentralized site, only to connect it with your FB identity?
To have a stop-gap measure against the chicken-and-egg problem. Connect it now, let your friends know that you are transitioning to this much cooler service and once a good number of them are there, then you will have enough momentum to cancel your FB account.
