There are ways to publish your articles automatically to Facebook and other social networking sites but as Google+ is new one, there is no such extension but I think you will get such extension within few months...
First of all, why would you use Google+ when you could be using Diaspora? LINK I do not think you could post a whole article yet, until somone makes a plugin. Your best bet would be to find a way to make a RSS feed. Let us know how it goes, but make sure you check out Diaspora first.
Go to the link and read... LINK It is an open source alternative to Facebook that is secure and your information remains yours. There is no longer a need for a middle man like Facebook, since it has been replaced with software. Freedom from the prying eyes of Facebook is also a nice feature. You can do what you want.
WoW... that sounds great... I was thinking about deleting my facebook account permanently and going for google+ but I think now i should go for Diaspora...
