I think on Wanikani there are Japanese learners studying for JLPT and those studying as a hobby. I am not sure about the distribution, though. But it doesn’t really matter because no matter what your goal is for learning Japanese, there are active threads on this forum that will help you achieve that goal.
So, what is your reason for learning Japanese?
One of my goals is to read novels in Japanese, so I will recommend the Book Clubs thread. In a few weeks, I will have more time to read novels, but for now, I am reading some manga so I also visit the Beginner’s Manga Book Club thread often. I am not actively reading along with these book clubs, but I find so many great recommendations for reading material here.
