This feels like another “WaniKani is too slow” post, just with a different name, so I’ve been inclined to ignore it just on that basis. I wish we would start closing a lot of these posts, because they’re all the same and it gets pretty tiring to see them over and over.
These types of suggestions aren’t to make WK better, they come from people who don’t like the core concept. If that’s the case, use something else. There’s no value in these types of posts when they are tied to something so fundamental.
If they don’t like WK, they can use Anki and customize to their heart’s content. It comes with the cost of having to maintain all the decks, add new cards, look for decks that may have disappeared, etc. WK is an alternative to having to do that. It is opinionated by design, so if someone disagrees with the opinions, then they can use something else that doesn’t have that.
Many of us have been using WK for years. We understand how it works and why and if it wasn’t effective, we wouldn’t be here. To have a brand new user who’s been using it for all of 5 minutes come in and tell everyone it’s wrong isn’t going to garner any meaningful responses. Feedback from experienced users (usually) is at least worth consideration, because it’s coming from someone who has a better understanding of the system.
I’ve had my list of hundred of similar threads I post to these every time, but it’s just not worth the effort even for that. Now I just flag off-topic and move on.
