It depends what you're doing. It shines on low level features like authentication and image cropping, where I need ways to do these things, and I can use them across the board. It breaks down when you have a lot of views and urls that are trying to stay close to their related models, but are too interconnected to have any real kind of separation of concerns. I find myself using all of the above. There's nothing wrong with building a small site in a single app, or nesting apps to provide a little more structure for how they're connected or separated.
