Caret — The address book for the 21st Century

Maybe this will be the app to give me a reason to spend more time in my Address Book. Article about Caret was on TC here: http://techcrunch.com/2015/09/17...

There was an app a while back, I think it was called "Human" that tried to do this, even offered updates from your contacts but it never took off. I'll have to give this a try and see if it works any better. It is really hard to improve on an address book.
