Great intro. One thing I don't understand about the mechanical keyboard community is how the vast majority (like well over 95%) are not split keyboards. You'd think keyboard enthusiasts that sweat the details would also be obsessed with ergonomics. But no, I suspect that they are more concerned with aesthetics, which are arguably worse with a split keyboard.
I'm also curious why there arne't more expiramental key layouts, for example having programming related keys like "()~!" on the number keys is kind of annoying, would love a redesign where they are on the left instead of say caps lock or a longer shift key.
I went with a 36 key Corne keyboard[0] with a modified Miryoku[1] layout. In this way every symbol is near the home row
