This is the third annual “state of the blog” review.

As the blog moves into its 4th year, how well is it achieving its goals? Is it succeeding in sharing concepts and methods across the multiple groups addressing complex real-world problems – groups including inter- and trans- disciplinarians, systems thinkers, action researchers and implementation scientists, as well as the myriad researchers working on complex environmental, health and other societal problems, who do not necessarily identify with these networks? Is it providing a forum to connect these disparate groups and individuals? Is it helping to build an international research community to improve how complex real-world problems are tackled?
