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.
The only other thing you need to do, other than add the circle to your profile, is occasionally go back to the circle and add it again (to the same circle in your profile) to get the newest list of people. Unfortunately, adding a shared circle only adds a copy of it at that moment, but not a dynamic one that updates itself.
It's not so bad though, because adding a circle to an existing circle simply adds in people not already in there.
I just found out about G+ adding limit. I tried to add the new circle that was just published and it said I have added too many today. Try again tomorrow.
