I have been a faithful follower of Class Based Views for years just until recently when I got completely immersed into the FBV way of thinking thanks to Luke Plant's excellent write up about Django Views - The Right Way:
It requires too much knowledge on part of the developer and is generally an abstraction for the sake of abstraction.
Simple functions are much clearer!
It was trivially easy to add authentication, caching, multiple response types and other magic without bothering the rest of the dev team.
Reading Luke's articles brought me back to FBVs, now I avoid CBVs whenever I can and feel happier for it.
The CCBV site from the original post seems nice and handy though.
Many people say that CBVs is Django on Rails but Rails doesn't use multiple inheritance or complicated MRO.
