If they ignore users too much it will lead to the death of Memrise.
From the book Code Clean by Robert C Martin a reference book for coding properly.
I know of one company that, in the late 80s,
wrote a killer app. It was very popular, and lots of
professionals bought and used it. But then the
release cycles began to stretch. Bugs were not
repaired from one release to the next. Load times
grew and crashes increased. I remember the day I
shut the product down in frustration and never
used it again. The company went out of business
a short time after that.
Two decades later I met one of the early employees of that company and asked him
what had happened. The answer confirmed my fears. They had rushed the product to
market and had made a huge mess in the code. As they added more and more features, the
code got worse and worse until they simply could not manage it any longer. It was the bad
code that brought the company down.
It look like Memrise here prioritising modifying designs over fixing bugs.
