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.

Either way, there is no privacy. It is always possible to take a screenshot, and share the screenshot publicly.

The only solution against it, which I'm able to come up with quickly, is Google Plus adding subtle watermarks identifying uniquely each recipient.

They should probably just change the default to disallow re-sharing on limited posts. I found the disable re-share option immediately but my wife didn't notice it due to the low contrast of the drop down button on each post.

I'm a little more concerned with the fact that you can see who a limited post was shared with by clicking on the limited link next to posts. It should be pretty simple to figure out who your friends have placed in their circles by looking at who their limited posts were shared with.
