Thing 9: Public Blogrolls

I am sorry, but I can't figure out why I would want to share my blogroll with anyone else. I can understand maybe sharing a feed suggestion but putting the whole roll out there? My blog is like a window to my soul and I am not sure I want to allow everyone to access all of my blogroll. Should I set up separate bloglines for my library community, my donkey friends, my fellow beaders? Am I alone in wanting to keep certain compartments of my life outside the limits of my fellow bloggers?
