Question : For-profit vs non-profit?

Our mission is clear : to expend the learning opportunities for all by connecting people with similar interests and by empowering people to reclaim their own education (and if the mission is actually not that clear, please comment on it !) This is obviously a social mission, and we believe deeply in the power of social entrepreneurship to change the world.

We have an efficient monetizing model, and we wonder: would our mission be best served by a for-profit model (based on social entrepreneurship) or a non-profit one? Why would you choose one over the other?
