> The key to Stack Overflow’s future and growth are the millions of developers from around the world who find the site useful, but who haven’t yet been welcomed into the community. We need to expand our reach and engagement to ensure these developers join the conversation and push their own learning to new heights.

The key to stack overflow's future is providing useful answers to various programming questions, facilitating the asking and answering of these questions, and providing an easy way to find the answers to your questions.
