I've admired and followed the work of Davied, a Dutch Civil Servant, for several years now. Davied has been using the internet for about as long as I have and (at least in my opinion) is one of the leading thinkers regarding Government 2.0 in Europe.
Davied was named Dutch Information Professional of the Year in 2009 and voted second most influential person in local Dutch government in 2010.He participates broadly in global discussions on Government 2.0 through sites such as Govloop and is active on Twitter as @Davied in both Dutch and English. Davied also runs the 6,500 member Civil Servant 2.0 network in The Netherlands and is an active proponent for Pleio, a free open-source system for governments to rapidly roll out Government 2.0 initiatives.
Over 25,000 copies of Davied's two books have been circulated in The Netherlands and Belgium. Now they are in English, I expect to see this increase rapidly.
To paraphrase Davied's blog post Dutch Civil Servant 2.0 books translated in English,
The book "Civil Servant 2.0" (originally released in Dutch in 2008) explains the significance of web 2.0 for government in terms of its internal organisation, its relationship with the public, and the working methods of the civil servant. It also contains a lot of examples from the Netherlands.
"Civil Servant 2.0 beta" (2009), is an extension of Davied's first book, providing a practical interpretation of the concepts expressed in the first book, and contains action points and ideas for government organisations to develop their own strategies for government 2.0.
I regard both books a must-read for Government 2.0 practitioners and would-be practitioners in Australia.
