It's sometimes said that if you aren't embarrassed by your product at launch then you've waited too long. It's important to get early feedback, and build on early reactions and responses.

Likewise, by making ideas like this, along with an early investigation, perhaps someone can build on it, or throw out another idea, and perhaps people can work together to find a good solution to the mess that is current user identification.

Or would you rather people beavered away in secret, never sharing ideas, never sharing their results, and never working together?

And it differs quite a bit based on _what_ I am typing, too. Plus the tactivity(?) of the keyboard factors in, because as soon as I have feedback that the key was registered, I am on to the next one.

Especially if a Dvorak user is forced to use Qwerty on another person's computer. At that point, they become completely unable to log in via this method.
