Last year, Microsoft revealed Office Delve, a sort of Google Now-like platform that surfaces important and timely information about work, organizations, and projects. Today, Microsoft is expanding Delve's reach into slightly new but still related territory. Like a social networking service, Delve's new People profiles give more in-depth insight into a person's activities. Delve is now also making room for blogs as a way to express ideas in a work environment. And Delve is now also doing the savvy thing and gets mobile, even smartwatch apps. Except on Windows Phone.
