Backward compatibility, compilation speed,
    circular dependencies, small vs big specs,
    etc. What code do you want to show about
    these aspects?

Code that shows these aspects. What broke in Java because of language changes and why. How handling circular dependencies in one language makes code uglier then in the other. Examples of the specs.

    You did the same with you "I love
    programming language" opening.

That I love programming languages and to reason about them is an information about myself that the reader does not know in advance. That choosing a programming language is not easy is public knowledge that the readers already know. At least if they are programmers.

That is the point of my post. Asking who the target audience is. And how it is different from myself.
