Every single person on this list is brilliant at what they do and a good communicator, with excellent s/n in their tweets. I've also removed people (like Jeremy Konyndyk, who otherwise I would recommend highly) who have a lot of insight but also a high emotional tone or a tendency to lean into politics. I've also tried to represent a wide range of expertise, from immunology to sequencing-based virology to public health specialists to frontline ER doctors.

So it's as close to a golden source of information as I could make it. I hope it's useful to some people, though I know the reach of it is a tiny fraction as if I made some dumb clickbait that happened to go viral.
