Windows 7 HomeGroup and social norms

A great post landed today from the Windows 7 Engineering team that made me stop my usual "partial-brain" scanning of daily information sources and actually read it slowly: At Home with HomeGroup in Windows 7. Not only was it well written and informative, but it shows the openness which blogging has brought about - insight into the team's thinking and processes. Their approach to looking at the technology problem from a social engineering perspective is great - I need to do more of this. How many times have we (ok, maybe just me) looked at a problem with thoughts of design patterns, technology approach, and which tools to use?
