There is a great article in Radar (a special blog-like section in the SMH) that quotes Cameron Reilly and provides a good summary of why organisations should have a blogging policy (a personal bug bear of mine). It is good to see some press in Australia on this, even if it is not 100% main stream.
Regina Miller is also looking for information of HR professionals who are implement blogs either internally or externally. I would also like to see the results of her requests. She also points us to some great comparisons of blogging policies, better than my attempts :-).
