Thanks for the feedback, everybody. In Windows 8, we wanted to provide a way for folks to view their photos on other services knowing there would be few (if any) apps in the store at launch that would do so. Now there are many apps in the store that offer ways to view photos on other services and soon there will even be a Facebook app from Facebook. We’re confident Facebook will offer great ways to view and engage socially with photos on Facebook. We welcome Flickr to do the same. In addition, the People app still offers the ability to socially engage with your friends and even your own photos.
Think of your Windows Phone ... the Pictures "App" is actually your Picture Hub. The one place you go to on your phone for pictures, regardless of where they reside. This is what the Pictures app used to be. Now it's not. We're going backward to where iOS and Android force you to be app centric instead of "content centric".
This is the way the People Hub works on Windows 8.1. You want to do anything related to a person, phone them, Skype them, check there Social status updates etc. you go to the People hub. You don't open each application individually.
This was a major bonus and draw card with Windows 8. Every time I demo that to someone they go ... WOW, amazing. This is so cool.
The Core apps like Photos, Music, Videos, Calendar, Mail, etc. should ALL be central Hubs where you go to interact with that content.
