The Windows Phone Youtube channel recently posted a cool video interview of Greg, the product manager in charge of the People Hub for Windows Phone 7. In Greg’s video you’ll get to hear a little bit about him as well as some thoughts and features that went into the People Hub experience for Windows Phone’s forthcoming “Mango” update. For example, things like the pinning a live tile of a person to a start screen lets you keep in touch with them better by having an animated status update or recent photo load. Then there are people groups that you can also pin to the start menu in order to keep track of a whole group of people. The contact history feature is also mentioned as a new way to keep track of all sorts of communications you might have had with a specific person.
