I think the key is something that will start by having the option to air everything you do on it on facebook also. People would be more open to change if it meant they could still keep up with both in the interim. I know when facebook was just starting out with people I know that a lot were happy to post actively on both, same with Twitter/facebook now. Long term I don't think people really want to but when something is new definatly. The other issue is monetising the new site, your selling points are also your ones which make being advertising supported hard, I think the aim would be to keep lean unlike the monolithic structure facebook has today.
