Are these ideas novel in the first place? Visualizing social sharing, dumping people in your network into piles (or groups as facebook called them)... they've been done before, it's no surprise Google might do them again too.
I do consider the interactive planner to be novel, as with currents which share the name as google currents.
More so than this, we have developed a system for identity management called Personas which we demo'd in Beijing a couple of months ago. All signs point to google releasing this system in the very near future despite claiming they wouldn't. I predict it will have the same name also.
