[racket] Blog post on learning Racket

Hi all,

I found this blog post by Artyom. The author, a Haskell programmer, has
documented their process of learning Racket (seemingly step-by-step
through the Guide).

It might have some insights on how we can improve the docs or language
to make it easier to pick up.

One idea I got from it is that an interactive DrRacket-based tutorial
might be a useful package to have (started looking into this a bit).
Alternatively, maybe our docs pages should be more interactive.

Cheers,
Asumu
