In preparation for SOCM2013, Dan and I performed a preliminary analysis of the wide and varied kinds of web sites, apps and online communities devised, broadly, to help people live healthier lives.  For this investigation we included  preventative wellness sites, sites and apps devised for disease management, crowd-based sensemaking, and categorised the purposes each served.  We also looked at the social components of these sites, specifically at the roles assumed by individuals and groups, and the roles of social (group) pressure and consensus in various kinds of support, such as disease intervention.

A draft pre-print of the paper is available here.
