GOOGLE PLUS APP UPDATE
Clearly every Google app has been updated to be more fitting of ICS. Today Google did the exact same thing to it's Google Plus app. Also taking a page from the new "Google Look". Everything seems to be a bit more modern and more eye catching. This is great as far as native apps to follow a more cohesive design to better the experience and make it more persistent throughout the OS. I hope to see Maps, Reader and any new app follow the same design pattern.
As far as the app. Google Plus is still awesome yet it still feels a bit out of place. Once you get over a certain amount of people in your circles you tend to loose tracks and it can become a less personal experience if you do not work at it. That being said the more time that you spend on the + the more you will love it and the more relationships you will have.
