Why you should follow him: Aase frequently opines about social media, both as it relates to healthcare and life in general, on his Social Media University, Global blog (also referred to as SMUG). It's his work at Mayo Clinic, though, that has everyone talking. The world-renowned hospital recently concluded its third-annual social media summit, which brought together social media advocates from across the nation, including several entries on this list. Aase's take on social media is simple: anyone can do it (and everyone should), but it needs to be a habit, not a fad.
