There are two schools of thought, in marketing, on giving away parts of your business, your ideas etc:

Give away your non-core ideas to attract people/resources/interest and then sell your complete system.

Give away your core ideas to "prove your worth" and build trust/authority/recognition and sell your complete system.

The second version is more powerful but it takes a leap of faith. Others could poach your work and use it against you but truly viable competitors are rare and people are lazy, the odds of this happening are often slim.
