Re: Repeat after me ...
To turn off seeing data which is already available, and simply presented in a different format? Who cares. If you don't want that data on FB, don't tell them about your relationship. But sine the entire point of a social network is to build connections, you've probably missed the point and shouldn't use the service.
If you don't use the service, then your commentary on what FB should or shouldn't do is fairly pointless. It'd be like someone who can't drive talking about what's wrong with the new Ferrari.
