 Designers and developers are needed to understand and explain the technological options available to online health communities and the implications of specific design choices.Such collaborations are needed to explore topics on which there seems to be no prevailing wisdom, such as how the nature of the disease or illness impacts the online health community design; how to improve health literacy; and which of the many collaborative technologies that are available best support peer interaction.Finally, it is important to track and evaluate new technologies, such as Web 2.0, to understand when and how to deploy technologies that assist in and improve peer health communication.
