I often read about all those RSI problems and then how pinky fingers have a lot of duties. I find it strange. I type at decent speed and I barely use my pinky fingers at all. I press Caps-Lock, Tab, Shift and Enter with them as well as | and }. Pinkies are small and weak, why use them so much? That's surely neither ergonomic nor the fastest way to type. It also means I don't like the idea of a split keyboard. I reach across quite often. I've never recorded myself to be 100% sure about all the keys but I am regularly reaching for b and y with both hands depending on the word. This way "typo" is just two quick "progressing" taps - "ty" with the left hand and "po" with the right. Of course "po" is way more comfortable with a ring-middle finger instead of a pinky/ring finger.

The whole idea of assigning keys to fingers doesn't sound too smart to me. Why would you type "ce" with the same finger? It's neither fast nor ergonomic. Why do it to yourself?

>Home row mods live in the base layer. In my opinion, home row mods are nearly essential to make a layout this small work well. The idea is simple: your home row keys act as normal keys when tapped, but double as modifiers when held.

I feel this is underexplored idea. After remapping my CapsLock to tap=Esc, hold=ctrl it went from the least used key on my keyboard to the most used one. I really like the idea of also doing it with home row keys, that must be very convenient after getting used to. That also seems completely free as you never (I think) hold those keys during normal computer use.
