I followed the link to the 'read this to see how to enable google plus' and that didn't even work. I then realized I had no idea if the google plus page I was looking at was 'new' or not. I did notice that all of the random stories from people I didn't know dissapeared.

All I'm left with is the pages from companies that are active on Google Plus in the attempt to give Google a social signal and sway Google's page rank in their favor.

Edit: to add, those companies are friend's companies and current and former employers. These companies asked all their employees to add them and get pester their social networks to add them as well.

The blog post has seven links to Google+. They just go to specific pieces or streams of content which are arguably more useful to demonstrating what's good about the new design.
