Interface designer Joshua Porter presents some interesting ideas regarding how software adoption works these days in the context of social media.  He deconstructs the social software adoption process into three separate stages that each require a different design philosophy.  The most interesting part of this presentation is how he frames the design problem as a social psychology problem whereby the friction of the user acquisition process is circumvented by leveraging concepts such as social leverage and community influence. Lots of examples.  Definitely worth flipping through.
