I am not sure people really optimise for speed, they do it for comfort. When I moved to dvorak my speed dropped by quite a bit and I never regained it but that was done for comfort, and it is more comfortable no doubt.

    I lost the speed because I wasn't doing as much documentation as I used to with qwerty.   For development, that loss of speed hasn't made any difference because I type just as fast for development purposes.

    But my main point is the people I know have not optimised things for speed, they have done it for comfort.  A ten hour trip in a plane takes the same time in business class as it does in economy but one is a nicer way to travel.

   I wouldnt run out and tell everyone to change their setup, people are usually driven to it for one reason or another, either just curious or have an issue they need to address but on a topic of ergonomics, thats exactly what ergo keyboards are about.
