QuantiaMD

It isn't common that I stick with a website for years, but I have been using QuantiaMD regularly for a while now. It is a community for health care practitioners (requiring an MD, DO, NP, or PA degree to sign up) with focused educational videos on many topics throughout medicine (from basic diagnosis and treatment of diseases to health care policy to physician well-being). Every field from radiology to surgery to oncology is covered. Participating in it leads to rewards, which makes it fun and engaging. The material is pretty solid and it awards CME credits. If you're interested, check it out: QuantiaMD. It does require you to verify your clinician status. Full disclosure - I do get a referral if you sign up.
