What's Happening in Silicon Valley?

I'm seeing more companies building things off of the address book rather than off a facebook or other established social grafts. I also think, i that we're seeing the whole live video phenomenon is really exciting to me,. But it's all the potential of it is always killed by notifications that just drive us crazy. And so i actually think one of the other sort of aras of levels of innovation is around notifications themselves. How can we make them smart and intelligent? What if you were only notified about something when artificial intelligence knew that you cared about it? Maybe even the cor operating system that we use will unlock things like lividio and other sorts of new modern social networks.
