I was particularly interested in the posts on "CSPS should have a channel on YouTube" and "Top Civil Servant talks to small groups & media - still avoiding 21st century notion of a 'blog'".
After having found the first one, I decided to do a little more digging around and came across this one as well.
Notable posts here are Civil Servants on Social Cites: Rules to Live By and PS Renewal and Social Networking (Again).
I encourage you to check them both out.
