So the question now is... does it matter if you have a Google+ page (setup for your business) linked as publisher or do you need to specifically have a 'person' G+ page linked as author?
Me personally, I have a G+ page, FB page, and twitter account for all my main sites... I do not link my personal/physical accounts on those sites which would just seem absurd to me. For as many idiots out there that take the time to whois a website and then use the 'wrong' contact info to ask questions when there is a huge contact form or support link on the site - this would go over great - not!
Not to mention this would be a huge target for spammers. Oh, John Doe's personal profile is linked to widget.com and it looks like he is from Austin, Texas... I think I will just spam him with postal mail and calls to his personal residence now regarding useless crap he won't be interested in for widget.com.
Sure hope this isn't true.
