More and more government agencies at the federal, state, and local levels are utilizing social media tools such as wikis and blogs.

A couple to note are intranet sites which, unfortunately, make them inaccessible to most of us. The first is Diplopedia billed as the Encyclopedia of the State Department. The second is Intellipedia which is a collaborative site for the intelligence community.

What I find interesting is that these sites were created because 1) agencies such as the State Department recognized the value of enabling individuals at all levels of the organization to easily contribute their expertise and knowledge and 2) it was felt that collaborative knowledge-capture tools like wikis could optimize timely reaction to security threats and terrorist activities on the part of agencies such as the CIA.

Take a look at the Case Studies page of the Collaboration Project, which looks at ways to utilize web 2.0 technologies to solve government's complex problems..
