Guide to Civic Leadership Blogging (2005 U.K. edition)
How to use weblogs as an effective local leadership tool
 
What to blog: Teach about a service, program, department
 
Government web sites usually provide an overwhelming amount of information on the services, programs and departments that serve the public.  This is usually in static form: HTML pages, PDF documents, pages of internal and external links.

But people still like to learn from other people. The demand for teachers (at all levels) is not diminishing in this age of information ubiquity. And a weblog post, written in the conversational tone of a personable teacher, can be the next best thing to a face-to-face conversation where the information is conveyed. (It also offers some things that a F2F conversation doesn't typically offer, namely links for the interested reader who wants to go deeper, and a record of the information that can be referred back to at one's leisure.)

So use your blog to teach. Help citizens see what their tax dollars are being spent on and the benefits accruing from it. Wrap your message around a recent story involving the names of people involved, if possible. Use photos and images to attract attention as well as to inform. And link, link, link – to web pages on your own organisation's web site as well as to other sites so people can easily go deeper if they want.

In the future when you need to revisit some aspect of the service, program, or department, you don't need to repeat yourself.  Just link to your own original post and expand from there.
