I’m so happy to see this on HN! I have nothing to add to the conversation except to say I’m a satisfied and dedicated user! I read a lot but I tend to read books that are “shorter” (~350) and finish them in 3-5 days so the huge classics can be intimidating and sometimes feel like a bit of a slog. I read on Serial Reader every morning while I have breakfast and I’ve finished 15 books this year on the app that I absolutely never would’ve bothered with otherwise. The $5 or whatever it costs to upgrade and read ahead is also well worth it. Sometimes you just need to know what happens next!
