I joined in 2011. Every year or so I remember TextFugu exists and come back to have a look. Yup, this and EtoEto are still as dead as ever. Koichi is still taking money from people on the back of lofty promises that hold no weight.
I know he says continually promising things is a bad idea, but if EtoEto was still actually being worked on, I reckon there’d at least be a yearly update Tweet to say “Yes, we’re still working on it”. This makes me think it’s also been abandoned. He got Viet to create WaniKani, and since Viet actually seems competent, it turned into a success and he doesn’t need to bother with the other stuff anymore.
