First, go and find out about Github. Figure out what it is they do, how they attract users, and how they make money. Github is already operating well in the Programming space, but perhaps the same basic ideas can be applied in the Cooking space. That's where you come in.

Edit: I think it's a great idea, it's just funny that that site mentioned this after only a couple refreshes.
