G+ has huge potential because it's Google's identity layer, the discrete social network thing is a byproduct.

I don't understand the distinction, isn't Google's account system still the same as before? So G+ is the need to attach a real name?

[X-X]

Yes - it gives google your real identity.

They've never had a proper picture profile integrated across all services, G+ solves that.

How about Google Profile before the G+? I actually find myself still using G+ in the same way I used Google Profile...

G+ is the overall system that links your Google profile to all your Google services.

It's Google Plus, and it does what the name says, it adds a new layer on top of all of Google.
