It lacks the fact that I can't communicate (even with Facebook's penetration) to probably a 25% of my friends.

Atleast 50% of my friends don't really get into the social networking. Either not having accounts or checking it once a week/month. I would say 95% of the people I now have email addresses and I can communicate with them.

When ever I see stats its always x amount of people use this per month. And I thinks for the same reason that exists in my friends. They don't care to much for that much about these sites.

I would guess over 90% of the content on FB is from 10% of my friends. The rest aren't so excited about it. So far none of my friends are really using Google+, and the ones that are I could say less about the content they are posting.

So I think you are misguided, and are under estimating how little interest a business is going to have towards storing there business data on what for many (including several of my own products) is a competitors system.

I think you misunderstood the point of the post, it's not that G+ will change everything today. It won't. It can't. It just started and most of my friends aren't on it either, but the technology and the UI they have come up with is quite enviable and we may be seeing the future of electronic communication. G+ is very well positioned to change email given the popularity of Gmail. Forgive my seemingly impetuous post, but I think we may be seeing the future.

Except for the obviously flaw where Gmails isn't as popular as you suggest. Having a lot less users than either Yahoo mail or Hotmail. Heres two links to verify that statement (second from google itself):

I'm not saying change isn't coming. I just don't think a Google social network will be it. Hell even there 18 million user announcement is quite average... thats under 10% of gmail users.

Considering MS has been spotted toying with implementing Social networks directly in Windows 8 (and with their share of FaceBook + Windows Live + Desktop OS we are talking massive users base).

A decent implementation could destroy all competition. The only ray of light there is MS history of failure.
