The article is interesting. I like the heatmap approach and trying to measure the physical differences between both keyboards. This is putting data behind a feeling and it helps looking for improvement. However for other parts of our body (like when going to the gym), I've been told to stretch as much as to exercise. I find odd the focus on reducing stretching in the article. I understand the issue for previously injured people and it is good that ergonomic keyboards and other hardware exist. While hitting the keys, our finger muscles get stronger in a specific movement, but like other muscles, they get shorter. Some stretching helps to keep a balance between strength and motion range. Would it be better to stretch our fingers after a long typing session, or even better, stretch while typing ;-) using some odd placed keys for their gym effect?
