Another social networking take on healthcare- this one has a platform approach for multiple communities exclusively for providers and professionals in the life sciences and healthcare industry. Within3 aims to facilitate ‘trusted relationships’ amongst its members.
What sets it apart from the usual networking websites is their business model (plus the fact that its aptly explained on a dedicated page) . Within3 is free to individual professionals, and earns revenue by selling software licenses to health and life science organizations who wish to establish online communities inside the platform. There are some nice examples of communities built on their platform- like med school alumni website, medical associations, etc.
