This looks like something out of the design team for Windows 8 (in both good and bad ways). It is visually striking, a dramatic simplification of what currently exists, and it makes several assumptions about the real world of what app developers need and how they can plug into OS-provided UI surfaces. One of the most painful learnings for Microsoft with Windows 8 was that overly-standardizing things like content sharing and tagging leads apps into situations where the affordances don’t work.
