Just got signed up for Google + (Google Plus ?) and started to explore. Its definitely an interesting concept that you can select your circles where you want your updates to be visible (i.e. family, friends, etc.).
Instead of having a work Google + account and a personal Google + account you could merge them into one and when you do status updates select which groups you are allowing to see you updates.
