I think the headline is accurate.

While we don't normally think of it as odd (probably because it happens on Facebook and other social networking sites all the time) Google+ was meant to protect privacy better than this, so it's a valid concern. And they're addressing it, as you noted.

I think you should be able to share links again, without giving access to all the comments and such. Pics and text should not be sharable... Without permission. I can imagine having things that I don't want to post 'public' but that I wouldn't mind friends sharing with friends I don't know.
