Nice article, but I disagree in the point that @@vars are simpler than 
class instance variables. Class instance variables have odd semantics in 
the current Ruby which means that they will probably do some detail 
different than you expect.

I've found that sticking to class instance variables (and thus keeping 
things simple -- why do we need another type of variables again?) helps 
in making code easier to understand.

Perhaps you should display both sides of this in the article.
