the problem is simple: no one wants to maintain multiple social accounts.
if all my friends migrated exclusively to G+, it would be fine, i would as well. but for that to happen, all of their friends would need to migrate...and so on.
i deleted my g+ account a week ago because no one has only a g+ account, everyone on g+ is ALSO on FB. as long as there continues to be a significant majority of content posted to FB (in my case over 90%), i have absolutely no desire to waste even more time being faux-social on an additional network. i have a real life as i am sure most people do.
i would need the equivalent of google reader to aggregate my social feeds so that i can stay sane. until that happens, "no thanks".

I'm a FB refugee and G+ is the first social network I don't have to maintain. It's just there. I use other G products anyway so I don't think about using or not using it, if having the account is really worth it. And circles are so damn easy I don't care about adding even whole public circles I wouldn't normally friend/follow on any other network - they are there, I don't share with them, I can read them once per month and their existence doesn't bother me, if I realize I don't read them, I can drop a whole circle 4000 people at once with two clicks. And it's usability is disobliging, especially comparing to FB.
if G+ has 90 million users, and FB has 900 million users. statistically, only 1/10th of your FB contacts would be on G+ without the help of warm-market recruitment.
if you happen to find yourself in a situation where 95% of your friends are either exclusively or primarily on G+, you are likely a rare exception and don't need to weigh a choice between following 95% of what your friends share and the freedom from "maintaining" a social account.
i am very specific about what i want to share and what i dont. for that to happen, yes you need to explicitly post and not post. i hate the whole "share everything implicitly" concept. to be honest, beyond the FB feed of my tight circle of friends, i don't use it for anything else.
Not following 95% of what my "friends" share was a decision I made way earlier. So I really don't mind that on G+ I have 10-15 daily posts from people I know IRL, not 650. And if facebookers came to G+, certainly over half of them would land in a separate circle of IRL people I'm not interested in reading for various reasons. Most of the mentioned problems with G+ are problems I don't have.
i don't FB friend people that i don't talk to IRL at least once every 6 months. in fact, i actively unfriend stale contacts every year (probably about 10% each time). i'm usually at around 75 contacts. so my "friends" are without quotes and actually those who i do care to follow.
if all my friends migrated exclusively to G+, it would be fine, i would as well. but for that to happen, all of their friends would need to migrate...and so on.
