One of my peers in the UK has just published a white paper on social networking in the Public sector. I've bookmarked it in our dogear social tagging system here
. But if you're not a registered user of this environment yet, you can get access to it directly here
Entitled, "Five million people around the water-cooler. How the UK public sector can harness the power of social networking
", it doesn't talk 'product' and is a good high-level paper discussing the value for this market sector. As someone who works in financial services I see the parallels in the value aspects.
As I pointed out in the 'comment' section of the bookmark in Dogear (our social bookmarking/tagging system) - the public sector in the UK (conscious of the international audience here and cultural differences...) relates to government departments and bodies.
This paper hits really the nail on the head in the conclusions,
"Social networking is not a technology it is about people and how they interact. For a social network to be successful, people will want and need to use it"
Technology for technologies sake will find it difficult to really address business and organisational challenges. The engagement of people is essential.
