Following on from few weeks ago where I presented some examples of Web 2.0 - 3.0 technologies and ideas being utilised in everyday life, I would like to continue that theme.  Highlighting how the 4C appraoch of social media implementation (from Niall Cook's - "Enterprise 2.0" - Communications, Cooperations, Collaboration & Connection) applies using a real world example. Last weekend I attended a "hackfest" set up by the SilverStripe Open-Source Community. SilverStripe is an open-source Content Management System (CMS) developed in Wellington, New Zealand and powers some high profile corporate and government websites. What makes SilverStripe unique though is the fact that their flagship product is free and open-source. Check out a quick video from Siguard , one of the founders for a great overview of their approach to software and open-source.
