The pressure curve and click placement on Cherry MX blues are generally conducive to learning to not bottom out on the keys and apply the proper amount of pressure to the key.

Bottoming out on the keys and using excessive force because of a lack of tactile feedback on the keypress are leading causes of injuries, because they provide a sudden jolt (when the key stops moving, but your finger doesn't) and unnecessary strain (to generate the extra force). Bottoming out in particular is bad, because you end up momentarily pressing against the keyboard frame with the full force you pressed down on the key, doing nothing but straining your wrist, while if you stop the downstroking on a spring loaded key before bottoming out, you'll end up stopping your motion in a cushioned manner (and the key assists a little bit in retraction).

Thanks for the info. I had never even heard of "hard typing."
