Dissemination 2.0: closing the gap between knowledge and practice with new media and marketing. 
Despite substantial investments in public health and clinical research at the national level, and significant advancements in these areas of science, few evidence-based programs and services are rapidly implemented in health care or public health practice as a result of failures of dissemination.  A significant gap in current processes to disseminate and implement effective programs relates to the lack of systems and infrastructure to facilitate distribution of scientific research products to potential end users, including clinicians and other practitioners.  In this article, the authors assert that Web 2.0 technologies can be leveraged to enhance dissemination efforts and increase the implementation of evidence-based programs and services in everyday practice.  The authors describe the research-to-practice delivery process and highlight gaps in the supply chain necessary to translate research findings into evidence-based practice.  The authors critically evaluate the 4 most prominent strategies currently used to promote dissemination and implementation of research evidence in practice, and they detail how each can be improved by leveraging Web 2.0 technologies to enhance dissemination of research evidence.  Last, the authors provide examples and suggestions for capitalizing on Web 2.0 technologies to enhance dissemination efforts and ensure that evidence-based research products reach intended end users and are implemented in clinical practice.
