Celebrity Net Worth says that Alexis Ohanian (co founder of Reddit) is only worth about 4 million dollars. Shouldn't the founder of such a large, influential site be worth much more? When compared to the founder of Tumblr, who is worth around 200 million, 4 million seems like a very small amount. Just wait until reddit hits 100 million users, sell ad space and go public, poof, instant billionaire.
