The document summarizes the results of a survey on the use of Yammer within the CPWF network. Key findings include that most users check Yammer once per day and find it useful for updates but not discussions. Barriers to greater engagement include time constraints and uncertainty around appropriate content. Recommendations focus on having basin representatives post weekly updates, forming smaller topic-focused groups, and continuing to use email for critical discussions. The overall goal is to enhance Yammer's value as a peer network for researchers.
