PatientsLikeMe.com allows patients to connect with others experiencing similar medical conditions to share stories, treatments, and side effects. By registering a profile, patients can find community and context for their disease while contributing data that researchers can use to study treatments. The social networking site has over 70,000 members across various conditions who openly share health histories to help each other and advance medical understanding. New members create a username and password during a two-step registration process to gain access to forums, treatment and symptom reports, and research updates within the site's seven sections.
