For posts written between spring 2008 and April 2010, I followed the principles for online engagement by UK civil servants when discussing work-related issues, as I was a civil servant. But since May 2010, I haven’t been.
More generally, I think Jeremy put it best:
This is not a political blog or a blog about politics. It reflects my views about the world I work in – overseeing web and digital media development for a UK government department.
I never knowingly publish any information that might contradict the Civil Service Code or my department’s employee terms and conditions.
My views do not reflect those of my employers – i.e., what I post is my opinion. This is, after all, my web site.
