[EDITED NAME] Sue, while I agree that Google has privacy issues like Facebook does, I think it's a different beast. One good thing about Google is that it's never been a walled garden that you can't escape. You can't export your facebook information, you can't even delete your account. You can only deactivate-- they still have your info. You can actually close and delete your Google+ and Google profile.
Secondly, while FB has lists, privacy in general was a backfilled feature for facebook. Lists are clumsy, not well-presented, and just do not offer a good UX. You can tell that Facebook has not put any emphasis on this, because key functionality (like reviewing who's in which lists, subdividing lists, editing lists) are still manual-intensive, inconsistent experiences on facebook. Google+ has the advantage of having privacy "baked in", so that you're adding people to circles as you add them to G+. While this is manual, it's much easier because it's as you add friends. Also if you think through your friends, clear segments arise. No one's forcing anyone to create a bunch of 5-8 person circles. Last, notice that Google+'s *beta* features are equivalent or better than facebook's so many years in.
10-person video chat is a premium feature that Skype members pay for (and Facebook hit back w/ their lame 1-to-1 video chat a week after G+ release).
Every gmail user sees the black bar at the top of their browser when reading email and using google search (and other tools). This gives them a notification every time they're added/friended or discussed on G+. This "toolbar" and its persistence is something that facebook would KILL for. This alone is a huge tool for Google+ adoption.
I think Google+ offers a good value proposition for some people, and it will be used in tandem with facebook. I think competition is good for customers and at the least, Facebook and G+ will improve. I think there's a possibility (maybe 20-30% with Google's investment) that some part of the US demographic (whether thats tech-savvy people or college students) will eventually only use G+ within 3 years.
