The reason we have the "QWERTY" keyboard is because on old typewriters, the rate at which people could hit the keys was faster than they could go up, hit the ribbon and return, before the next keys came up. That was an engineering design decision based on that technology. A guy named Dvorak came up with an optimized keyboard, and...
found that it took an average of only 52 hours of retraining for those typists' speeds on the Dvorak keyboard to reach their average speeds on the qwerty keyboard. By the end of the study their Dvorak speeds were
74 percent faster than their qwerty speeds,
and their accuracies had increased by 68 percent.
If people were trained and used the Dvorak Simplified Keyboard in the first place, we could dodge that retraining, and make incorrect posts even faster on the internet.
