I suspect that no answer will make you happy here, since a social network "getting it right" is where all the people are. You can't be getting it right if a significant number of people aren't there, and you can't be a competitor unless you're getting it right (the threshold for 'significant' seems to mainly depend on which network you personally use ;P).
I'm one of those strange people who is perfectly happy on G+. I was 'friends' with a significantly larger number of people I knew in meatspace when I was on Facebook compared to G+, but they were people I had lost touch with for a reason (regardless if whether that was my fault or theirs). G+ has allowed me to follow and interact with a broader range of interesting people that I don't know personally or event tangentially, and so to me, that makes it a much more useful social network that Facebook ever was.
