You missed the point. Your original comment was an oversimplification of how people interact, similar to the argument "If you're not doing anything bad, you have nothing to hide." The way people interact with other people can not be reduced to a finite set of values, such as "friend or not friend" or "family member, lover, friend, acquaintance, co-worker". In other words, this is not a Facebook vs. G+ dilemma. The problem here is the fact that Facebook has, yet again, limited the way we interact with other people by imposing their own structure and rules: if you don't want a person to know you're paying attention to them, don't pay attention to them. Your proposed solution of "don't add them as a friend" is even more restricted. Maybe it's your way of interacting with people, but I don't see how it's justified to try to impose it on everyone else.
