Wow! It's exciting to see Chicago Public Media's (@WBEZ) Breeze Richardson SO inspired by Joy Mayer's RJI Engagement Metric event this past spring (2010) she's created a new Chicago case study. http://www.rjionline.org/blog/measuring-community-engagement-case-study-chicago-public-media

Breeze shares the work has a "goal to demonstrate how engagement impacts civic health and increases the local significance of the station as a community institution: In the report that resulted from the Engagement Metric conference, it was eloquently put: '… as news organizations fight for survival, a more connected relationship with communities should be valued, and therefore measured.' At Chicago Public Media, I have identified five areas of measurement [of community engagement]...in short they encompass:

Station partnerships and collaborations,
Audience commenting online,
Audience participation in content creation,
Audience recommending content online, and
The production of station events..."

Check it out.

Joy -- what will you inspire next?
