Anyone who has taken a class with Professor Powell knows that marketing is, “finding out what people want, and then giving it to them.” Stumbleupon does just this. With Stumbleupon, you plug in some initial interests, and then it brings up websites that you might like. As it learns what you like, it will bring you more of what you like and less of what you don’t like.
This process helps make their promoted websites more effective and less bothersome. Usually people hate advertisements or promoted websites, but in the case of Stumbleupon, they are finding out what you want, and then giving it to you, and sometimes they get paid for it…what a great business model.
