Free Software is good but on its own isn't enough.
When you look at the definition of Free Software you will notice how it is very programmer centric in its sense of freedom.
Those who can't program and don't have the time to acquire the skill are directly excluded from most of the freedom we associate with Free Software.
The only freedom they have is to run a free program and redistribute it without restriction.
If your software could be useful to non-technical people, make sure they still have access to the participatory part of Software Freedom.
Write accessible documentation.
Provide ways for non-technical people to contribute to your project.
And most importantly: Listen to the feedback of non-technical users equally, if not more than that of technical people.
