https://techcrunch.com/2020/04/02/pinterest-ceo-and-a-team-of-leading-scientists-launch-a-self-reporting-covid-19-tracking-app/ > There have been a few scattered efforts to leverage crowd-sourced self-reporting of symptoms as a way to potentially predict and chart the progress of COVID-19 across the U.S., and around the world. A new effort looks like the most comprehensive, well-organized and credibly backed yet, however – and it’s been developed in part by Pinterest co-founder and CEO Ben Silbermann. > Silbermann and a team from Pinterest enlisted the help of high school friend, and CRISPR gene-editing pioneer / MIT and Harvard Broad Institute member Dr. Feng Zhang to build what Silbermann termed in a press release a “bridge between citizens and scientists.” The result is the ‘How We Feel’ app that Silbermann developed along with input from Zhang, and a long list of well-regarded public health, computer science, therapeutics, social sincere and medical professors from Harvard, Stanford, MIT, Weill Cornell and more.
