Jordan, beautiful are your ideas and suggestions, but unfortunately, I think
that they are futile. Why do I say this? I think that Racket primarily serves
to a specific group of people as an inexhaustible source for mass-production of
always the same academic articles, and much less for everyday, practical
programming.
But to get back to Danny's question:
I think it would be most useful that, after the "Continue" tutorial, follows
one realistic example of more complex web application, through a detailed story
about how and why it was made just that way.
Of course, that hypotetical advanced tutorial should explain to people how to
get a "nice" URLs, how to "ajaxify" application, how to cache certain parts of
the rendered page, etc, etc.
And it should conclude with discussion about how to achieve high scalability
(for example, how to create a new Twitter in Racket, with millions of users!).
