For all the shit that the desktop web experience gets, the mobile web experience on reddit is a 1000 times worse. It sometimes blocks you from viewing certain (cough NSFW cough) subreddits unless you use the app, umm what??
Even worse that most communities, even safe for work ones like gaming communities are locked being using the app. I can't access any of my favored subreddits on mobile without visiting the old site.
The good thing is that refusing to download the app has cleared me of my reddit addiction
Not only that, they also have some A/B testing in place which makes email id mandatory if you signup via mobile browser; of-course email id is not needed for mobile app.
I also found that the mobile dials home quite regularly when in background.
