Todo lists do have business logic, but the logic is so simple that one might not notice when it gets coupled to the views. so you can get away with coupling things like "MV-whatever" or MVVM for apps up to a certain threshold. Facebook is an example of an app well past that threshold, so we should probably listen to them when they talk about their new DOM management library, Facebook React.
