Most of what has MVC slapped on it doesn’t even resemble that original design and the division of responsibilities doesn’t map well to what kinds of things happen in web applications. In general I think when you have the amount of difficulty in explaining what you’re trying to do that MVC advocates always seem to have, you’re doing something wrong.

I think in terms of filters, transforms, and templates (which are all kind of the same thing). Mix some data and a template. Filter something. Combine every element of X with the corresponding element of Y. That kind of thing. If you can’t explain it to someone who knows nothing about computers with simple block diagrams, you don’t really understand it.
