HealthBoars is a long-running support group website consisting of over 150 Internet message boards for peer to peer health support (also referred to as a virtual community or online health community). The site is unique in that it is purely a health community site, unlike other established health communities on the Web which have generally been part of large web portals (WebMD, Yahoo, iVillage, etc.). As of June 2006 the site received over 2.3 million messages posted by over 250,000 registered members. In 2004 HealthBoards established a partnership with WebMD to provide additional health content and advertising support for HealthBoards. HealthBoards is currently ranked in the top 20,000 websites worldwide in terms of traffic by Alexa.
