Facebook for Windows 8 isn't very good

The app itself seems fine, but it doesn't have any of the hooks into the system that I would expect from a well made app. It doesn't show up as a target in the share menu and it doesn't show up as an image source in the file picker like the photos app used to in 8.0. I hope this is just a first pass by Facebook and they intend to update with real system integration before too long because as-is this app really offers no advantage over just using the website in IE.
