https://plus.google.com/106419647632534512037/posts it's just a page. if I understand correctly what's going on on the page, we need to add people to our own circle every time they publish the updated circle.
//edit:
it looks fine except people who write public posts in their native language which I do not understand. I hope the author thought about spam prevention or we'll get lots of 'funny videos and pictures' profiles in there soon.
They need to separate functionality. Right now you aren't following a shared circle. Adding a shared circle creates a whole new circle that you can modify however you want. I want it to work more like Twitter's lists. Not that I mind the 2000+ circlings I've gotten from shares. :)
I wish posts had a native language the are posted in, since I have friends in Mexico that post things both in English and Spanish, I have no desire to grok their Spanish posts, so the ability to filter circles or the main stream based on certain things is something Google+ as a whole needs.
