It shows that some of the sleeker design decisions have not been accepted well it seems. A reminder to us UX Designer to continue to improve and test our designs.
Fonts always have an implied use case ... as designers we should honor that and use fonts that help the messge of our design. So, use this font to add some coolness.
Anyway - if a user has installed the Google+ Notification Chrome extension he will have the posibility to add the Google+ Page of a linked website directly while visiting. It's sounds complicated but should actually make it easier for users.
This is an important step - and the right strategy. To open it just for selected third party tools will help to save Google+ from becoming the automatic update dump that Twitter has become.
I'm curious to see if there will be the same outcry on google+ with the new design as you always hear on Facebook - but I like it.
