I tried appollo a while back and I was not a fan. My biggest gripe with the UI of appolo and post-redesigned reddit is that it feels like instagram or a facebook. I don't like endlessly scrolling through pictures and auto-playing videos since most of them are of no interest to me. If I want to view a picture/video I'll click on it. It clutters up the page with content I don't care about. Mobile browsing (for me at least) is already a slower and more tedious process because less items can be displayed on the screen at once than a full desktop version, and typing/navigating is considerably faster with a physical keyboard and mouse.
