It more looks like you hit a stonewall and decided to turn your car back off instead of trying to get through, because it’s physically impossible. In the thousand comments long thread no one (!) supported the Decks idea without the apps. You knew very well that you warned only a small fraction of users about upcoming revolution, so it was only the beginning of a pretty big downfall. Therefore your latest decision is very logical in itself.
Still it does not mean that you will actually listen to users and improve user created courses, because you are intending to build a super innovative language learning app/website for so called “tourists” (sorry, guys, no offence). You absolutely forget about the other side of Memrise two-three years ago. Look around for the requested features - you are ignoring them all for a long time. I might sound a little pessimistic, but prove me I’m wrong.
