jobs - Usability/UX elevator pitch?

Whenever I try to introduce someone to usability/ux, I always find myself having to explain the following:

1. The definition of usability/ux.


2. The fact that I make web site easier and more pleasant to use.


3. Give some examples of how this is accomplished.


4. Maybe mention some unusable site so they can relate to what I'm saying.


5. Explain some of the benefits of investing in usability.

And although I end up clarifying all of these stuff, it takes a lot of time (about 5-10 minutes on average), especially point 3.

Do you think there's a way to sum up all of these points in a quick 30-seconds elevator pitch?

I also need this for my usability/ux blog to quickly explain what it's all about to new users.

Appreciate your input :)
