Are you going to tell us all books about your pet language are worth their price? How is that the community's problem?
All of this will not happen, of course, because there is no such application written in the Racket in the world (no wonder when the documentation is so awful!)
When there's at least one, let me know.
Believe what? I've said nothing hinting at racket being good for web programming. What I do say is that you are missing the forest for the tree. You should probably go back to rails or django, as you'll be much happier there.
And if like your username and debate abilities suggest you are really 20 years old you can't present yourself as "an experienced developer", sorry for being blunt. Regarding Racket at least, you have a lot left to learn.
