Google Reader can let users share the post with the friends.
Actually, it is not the friends list. It shares to all the contacts you have.
But, not all contacts are your friends. OK
Google fix this bug now.
User can pick the friends from the contact list.
People that you add to the Friends list will be able to automatically see your shared items in Reader (remember, shared items always have a public URL).
