She has over 200,000 followers on Twitter and over 300,000 on Instagram. Compare that to her peers: Laura Osnes has 60k, Cynthia Erivo 40k and former Amélie Samantha Barks has 160k, despite starring in one of the biggest movies of 2012. The difference is just because people know someone doesn't mean they'll pay to see them in a weak show. The poor box office results clearly are to do with the negative reception towards the show itself and not to do with Soo.

This doesn't really prove how well known she is. I'm not sure what her follower numbers were before Hamilton, but all of the main cast members (and even some of the ensemble) received significant increases in followers due to the hype and popularity of the show. Audra McDonald, Sutton Foster, and Laura Benanti all have less followers too but I'm willing to bet they are far better known regionally and nationally than Soo.
