The Guardian ran an article on Google+ on 20 Sep 2011 after Google announced that Google+ was now open to the public (the invitation only beta phase had been completed).
I am still experimenting with Google+ having had one or two teething problems with the beta.
The current view is that the Beta has been extremely successful with over 20 million people signing up in 12 weeks. One of the very interesting innovations is the “Hangout” which is a group video conference facility.
The big question is what can it do for business? I think it needs to maintain its growth momentum for a start but at present Google has actively discouraged businesses from setting up accounts and has insisted on real names being used on the platform (instead of code like “Happyuser123”).
I have pre-ordered a Chris Brogan book (link to his website and an article by him on using Google+) which is due out in early December entitled “please come over to my site and join my mailing list. You can comment below or email me at john[at]jbdcolley[dot]com.
