Gmail was very successful with it's invitation system: it was elitist, and everyone ached to get in...
What your analysis misses is that Gmail actually addressed a pressing need in the free email marketplace: space. On top of offering an order of magnitude more storage than its competitors, GMail also brought distinct improvements to the email paradigm (tagging, search, spam filtering). That allowed it to attract users from Hotmail/Yahoo and even private web hosts.
If I knew what the pressing need of the social networking marketplace was, I wouldn't post it on Slashdot. Facebook was weak in terms of privacy and controlling the spread of your information, but G+'s circles weren't a killer app. And everything else on G+ is just a Facebook clone.
I wouldn't count G+ out just yet. It's Google after all. Those millions of inactive users could quickly become active if G+ somehow jumps ahead of the curve.
