In a one-story concrete industrial building across the street from a lumberyard in Austin, Texas, Greg Matthews and his computers are tracking everything that more than 500,000 U.S.-based physicians post publicly on social media. Every tweet. Every public blog, Facebook, or Instagram post. Every YouTube video.
If you’re a U.S. physician and active on social media, Mr. Matthews likely has your public posts on file. Did you comment on a colleague’s paper? Discuss a new drug? Answer a patient’s question? It’s in there.
