Happy Crystal user and code contributor here. (Also created https://github.com/compumike/crystal-docker-quickstart in case you want to try Crystal without installing anything.) In my opinion:
- Slow compile times are still a pain for iteration.
- The REPL / interpreter mode is still rough around the edges.
As far as companies using Crystal:
- We’re using it happily in production at Heii On-Call https://heiioncall.com/status
- Kagi is using it for their search engine backend https://news.ycombinator.com/item?id=32687071
- Other companies using it list: https://crystal-lang.org/used_in_prod/

Crystal for Rubyists
This is great Serdar.
As an alternative to Chapter 2 I’ll also share https://github.com/compumike/crystal-docker-quickstart my project template which lets you get a Crystal (currently 1.6.2) dev environment running with just Docker. Good for kicking the tires, which is what I think your audience is probably wanting to do! And then eventually can install a binary package as you suggest.

Marten, a Crystal web framework that makes building web apps productive and fun
My side project https://totalrealreturns.com/ is now about 5k lines of Crystal. There are some rough edges: in particular I think it could use a better templating solution (a port of HAML would be ideal!), and there are some failure modes with the Redis connection pool that have required workarounds.
This includes unit tests: the built-in spec framework is great and much like rspec. https://crystal-lang.org/reference/1.6/guides/testing.html
I'm now starting to use Crystal for internal backend infrastructure and microservices.
For anyone who wants to kick the tires on Crystal, I built a crystal-docker-quickstart project template: https://github.com/compumike/crystal-docker-quickstart works without having to install anything locally. (Assuming you have docker.) You can have your own, home-built "Hello world" static binary in under a minute:
git clone https://github.com/compumike/crystal-docker-quickstart.git my_app && cd my_app && ./d_dev
- crystal-docker-quickstart: try Crystal in a container, without installing anything

Crystal Programming Language
If you'd like to try out Crystal without installing anything locally, I've created a tiny Docker container with a Crystal project template:
https://github.com/compumike/crystal-docker-quickstart
For example, you may do:
git clone https://github.com/compumike/crystal-docker-quickstart.git my_app

Phoenix on Rails - a Phoenix tutorial for Rails developers
https://luckyframework.org/ . Kemal is even faster but it's mostly for APIs. In my opinion it's on par with Actix with much, much better developer experience.

How do you find the market in 2023?
It's been around for a while under development. It had it's 1.0.0 release in March 2021. There's been two (online) Crystal conferences, and there's two Crystal books published. There's a decent ecosystem of "shards" and there are a couple of Crystal web frameworks and ORMS that are similar to Sinatra or Rails-like. If you already know Ruby, learning Crystal is super easy.
- Kemal: Fast, Effective, Simple Web Framework for Crystal

Marten, a Crystal web framework that makes building web apps productive and fun
They’re all good to try IMO, another is https://kemalcr.com which is akin to Sinatra if you just want to get an HTTP server with routes setup quickly.
