I do the same thing as the author. If I see that the comment stream is somehow related to my FB account, I skip commenting. I don't know how they're used or how they feed into some other FB stream.
Even if I did have a feel for how those comments currently are integrated with other FB comment streams, none of us has any idea of how FB will change their policies in the future that will totally wreck our personal notions of "separation of concerns".
