What is Developer Program Member?

I have seen a couple of Github profiles having "Developer Program Member", can anyone explain what is the essence of this and how it works?

GitHub Developer Program - This is a program that developers join who build tools that integrate with GitHub.

This is for developers registered to the GitHub Developer Program
That allows for:

Staying in the know:
Be the first to know about API changes and try out new features before they launch.

Scratching an itch
Build your own tools that seamlessly integrate with the place you push code every day.

Taking on the enterprise:
Obtain developer licenses to build and test your application against GitHub Enterprise.
