Advantages of Models

I'm with jalaski on the model issue. Models shouldn't even know their on a web server (realize that the database class handles that). No emailing. No session handling. Nada. Just get data, store data, validate data (in a way). No getting post or get.

But I still wouldn't say, "If the controller is appearing a little bloated, it’s a sign that it’s time look at moving some stuff to a library, plugin or helper." Just because there's a lot of code doesn't mean it's all abstractible; there could be a lot going on. Even if it is, it doesn't mean it should be abstracted (it doesn't all come down to DRY; flexibility needs to be considered, among other things).
