It's now been three weeks since Google launched its new social networking site, Google+.
The company won't say how many people have signed up,
but Paul Allen, the co-founder of Ancestry.com, shows us, gives us a rough idea of what the growth rate has been.
This shows you back in June there was absolutely nothing. G+ was unknown.
By the time we move on, it is officially announced and it is really making a lot of buzz.
It comes off slightly a bit with the tech reviews. This is, by the way, the number of searches that there are on Google for G+.
Carry on, and it goes back up again. And that's the way Google continues... the new G+ continues.
What it shows us -- they estimate, judging by the number of searches, that there are roughly 10 million users of this at the moment.
So, what are the key features of Google+ that everybody is looking towards?
It really comes down to these major features.
First of all, you can have circles. Never mind lists and groups, you drag people into your ski, your San Diego, your family.
You can basically get people to be where you want. It has video phone calls, video conferencing, video chat.
Facebook has immediately countered with something of... something similar, with Skype.
And, of course, it allows you to send group texts through your circle.
So these are the three things that really make it very different. And it's these things that perhaps have given the 10 million users the interest that they've come along with.
Eric Schmidt admits Google should have gotten into this a lot sooner, as he told us.
The revolution that is mobile has just begun. In all of these countries, especially in Asia, mobile penetration is very, very high and, in fact, growing even faster.
And the new generation of phones is so much more capable.
So we're going from a situation where the average citizen didn't have that much power to a point where they can know everything and they can organize very quickly.
And that may bring down a government, as in the case of the Arab spring, but it may also just challenge vested interests and so forth in a democracy.
So does that mean the PC is dead?
Well, the PC will be used for things where you need to do a lot of typing, because it's hard to type on that glass screen.
But for everything else, you're going to be using a mobile device, a tablet or a mobile phone or some kind of mobile small thing that you'll carry around.
They're inherently better. They're more personal. They... with your permission, they know who you are, they can make suggestions to you, that kind of thing.
Do you see Facebook as a major challenger to Google?
Fundamentally, what Facebook has done is built a way for you to figure out who people are.
That system is missing in the Internet as a whole. Google should have worked on this earlier.
We now have a product called Google+, which has been in development for more than a year and a half, which is a partial answer to that.
But I think that's the area where I would have put more resources.
