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.
Removing the functionality of the photo app to the point of rendering it useless was a mistake.
Considering how much effort must have gone in to gutting it compared to how much effort would have been required to leave it as is, it's hard to imagine some making that choice.
People are skeptical enough about windows 8 and 8.1. I can't believe someone at Microsoft would make the decision to remove functionality that (judging by the posts in this thread) people found very useful.
