This study offers interesting conclusions about the success of different types of online communications at non-profits. For those interested in the types of metrics available to evaluate such communications strategies, this study is quite useful. The complex methodology of the study might be more interesting to someone who has already done some communications evaluations, but the “Glossary of Terms” is a good resource to supplement other introductory materials for someone who is first exploring the field.  - Caroline Lewis, ReThink Media
