Comment 13 for bug 346095

I have a question...on one of your blog you have following:

http://mpt.net.nz/archive/2008/08/11/usability

It’s unhelpful because usability has multiple components:

    * Learnability — how easily a beginner can use the system, and how easily they can become an expert.
    * Efficiency — how quickly people can achieve what they want.
    * Memorability — how easily people can remember how to use the system or feature, after not using it for a while.
    * Safety — how rarely people experience errors, and how easy it is to fix any errors.
    * Satisfaction — how pleased people are with the overall experience.

Can you please explain how not providing an option helps with usability?
