I'm not a social person, so maybe I wasn't a target audience of Google+, but for all its flaws I actually loved asymmetrical following model. That means I can "follow" a friend of college friend whom I might have met twice, just because they say something interesting, without wondering "Wait do I still count as their friend? What if they remember me and I really don't? It's gonna be awkward..." Similarly these kind-of-friends can follow me because they find me interesting and I'll feel no pressure to follow them back. Half of the time I get a friend request in Facebook, I don't really know the person (but I have reasons to expect that the person thinks they "know" me) so it feels awkward either to accept or decline. Just my two cents.
