After browsing some source code (namely danbooru's source, and other random projects), I'd like to learn more about "Model-View-Controller". The problem is that I perused Wikipedia's article on the subject, but after reading the discussion page I found out that it amounts to nothing and has no practical worth.
Thus, the problem is that I'm a little bit confused as to where to get good introductory material on MVC. Does anyone have any book, article or other reading stuff to suggest?
