title: in MVC/MVP/MVPC where do you put your business logic?
body: <p>in the MVC/MVP/MVPC design pattern where do you put your business logic? No, I do not mean the ASP.NET MVC Framework (aka "Tag Soup"). </p>
  
  <p>Some people say you should put it in the "Controller" in MVC/MVPC or "Presenter". But, others think it should be part of the Model. </p>
  
  <p>What do you think and why?</p>
