Comment "Touch typing" considered harmful (Score 1) 191
"Touch typing" can mean different things.
The typing schools teach that there are supposed to be diagonal columns of keys on the keyboard, and that you should use only one finger per column (... except for each index finger and each pinkie having two columns each).
But the typewriter keyboard was never designed with any columns in mind. The keys were mounted on mechanical levers and the layout was simply a consequence of getting the levers equally spaced.
If you'd force yourself to use the school method, your left wrist would have to be kept in an unnatural angle for a long time, which could cause strain injuries later on.
That is why some "ergonomic" keyboards -- made for school-"touch typists" -- have the keys in actual columns.
For the rest of us, who just learn to "type without looking", we learn other habits, and develop other muscle memory.
If you use computers much, I think that you should definitely learn to do that.
Then the regular typewriter layout is ergonomic enough.
That said, I've worked with people who were very good programmers but slow typists. Programming is mostly about thinking, not typing.
