From now on you can share your Google +circles with any contact. As you know, the circles would foster a substantial improvement in the social network usage, and nice way to organize contacts in the form of lists.
Google engineer Owen Prater, commented on video to share those lists is simple by just adding an optional comment in the circle and select the ‘Share’ (Share). Thus, the circle with all the contacts that houses will be posted on the timeline of the user.
And what about the privacy issue?, You may ask. The name will remain private circle and each user who receives the circle may arrange to your liking, adding or removing contacts. You can understand it better when you see the explanatory video.
“It is possible that my U.S. – non-U.S. ratio is off slightly,” says Allen. “And it is possible that my 15% fudge factor for private profiles and for non-Roman characters could be way off.”
That said, he has taken pains to demonstrate how his methodology – which looks at the occurrence of rare last names – yield on-target results, even if he can’t pinpoint the user count. According to his estimates, the site boomed from 43.4 million users on September 22nd to over 50 million on September 25th. The reason boils down to Google+ being opened to the public.
Hitwise showed a similar boom; according to their analysis, Plus saw a 1,200% increase in traffic after it opened its doors to all users. Hitwise has yet to respond to an inquiry on whether this examines the front page or all pages, but I would assume they’re referring to the plus.google.com page itself.
In any case, it’s evident that Google is getting a rush of users now that it’s not invite-only; Allen suggests that there has been a 4 percent daily growth, equating to about 2 million user registrations each day since the public launch.
