Seems like a well-done service, but I would think that user management is far too strategic for most businesses to hand off to a third party.
My impression is that most people use OAuth-type authentication schemes not because they are worried about the complexities of user management, but rather that they want to gain access to the resources that those enable. In the case of Facebook and Twitter, authenticating with them provides access to new distribution channels, which is really the entire reason they are interesting in the first place.
