So I actually worked at Reddit a few years ago and our “cohort” got to chat with Steve as a part of onboarding. I was super nervous and I guess I wanted to appear sharper than I actually was, so I asked Steve directly “why do you push users from mobile web to the app? That’s a pretty bad experience.”
Apparently there are metrics showing that mobile app users are “stickier” than web users, meaning they come back to the app more.
That was a long time ago though and my perspective on this probably isn’t relevant anymore.
