Social media has become an important tool for physicians and scientists to rapidly share information with colleagues around the world. Use of social media outlets-in particular, Twitter-has risen rapidly in recent years, and it is now customary for national hematology meetings to have thousands of participants who share photographs and textual summaries of data presentations, as well as personal insights and commentary, with virtual audiences. These messages, or "tweets," can be specifically followed using a hashtag ontology which arose organically over the past several years in the context of medical meetings. This system facilitates communication between meeting attendees and those colleagues near and far with similar interests, thus globalizing the conversation between hematology providers, investigators, patient advocates, professional organizations, regulatory agencies, testing companies, and the pharmaceutical industry about cutting-edge developments in the field.
