Cities using the Web to engage

I stumbled across this blog, A Better Oakland, yesterday. It seems to me that a blog like this is a wonderful way to start engaging people in a wider discussion about their city and its development. Cities will spend hundreds of thousands of dollars on PR, they will hire consultants and do all the traditional stuff but how about just starting to dialogue with residents? Nothing overly formal. Just a daily or 2-3 times a week journal with reflections on the issues of the day.

No brainer, right?
