I thought I tried to try out the web version. I don't have a throw away phone number, so I didn't sign up, so I didn't try it out.

My suggestion for facilitating feedback is to have a tour or a lower friction signup even if that means reduced functionality or simulating parts of the app. I mean, the landing page knew I was coming from Hacker News, so instead of coding up a popup to tell me that [I already knew it], why not dump me into something to play with?

Good luck.
