Racket is just awesome. I don't know why it doesn't see more use. That list of features is awesome. This, just a few months since they redid all of Racket's graphics library. Well done!

I use Racket to study SICP so I haven't looked into the Racket language at all, but I can give you my impressions about the programming environment. On my netbook running Ubuntu, DrRacket is extremely slow and short keys don't work. I've found how to use the racket interpreter using (enter! "myfile.scm") and how to enable readline support, but it wasn't obvious at first. On my laptop also running Ubuntu, DrRacket is usable but strangely (enter! ...) raises an error. This gives the impression that the whole environment is not well polished. I think it would be useful to have an easy-to-find straightforward tutorial on how to use Racket with any editor and the text-based REPL, as many people are probably not keen on using DrRacket.
This is not a criticism or even an opinion but merely a feeling I'm expressing here, I'm sure I could (and will) address all these issues with more RTFM.
Just a quick note: enter! doesn't really make sense in DrRacket. When you evaluate your code in DrRacket it does the equivalent of an enter! for you. If you want help drop into #racket. I'll be there in a couple of hours.
Oh I don't know, it's not completely obscure. Tools like DrRacket need a community to exist, they don't come from nowhere. It's used at a reasonable number of schools, and even has a book about interpreters written with it (by Shriram Krishnamurthi).
Now if you're asking why it hasn't replaces Scheme, I personally think it's (1) because Racket is yet-another-lisp-derivative, (2) because adding objects to lisp is like a rite of passage for lisp programmers, which trivializes many (cool) features in racket, and (3) because it's hard to convince old-school lispers of anything, let alone that their dialect is wrong, or needs improvement.
Does anyone know of a few good examples of using Racket's GUI and drawing/canvas library? I took a look at it a few weeks ago, in the hopes of coming up with a portable way to do simple graphics examples, such as turtles and life and drawing character, but it felt like it would take a lot of study to get anything working. (I've done more curses than Tk, and more Tk than Swing, and not much else.)
