I feel the same way about Elixir here's why:

- docs

- testing

- Slack chan, IRC, mailing list

- package manager (Hex)

- build tool (Mix)

- web framework (plug & Phoenix)

- db framework (ecto)

- books from major publishers (manning, pragprog, etc.)

- ElixirConf

- ancillary teaching (ElixirSips, LearnElixir, Elixir Fountain, etc.)

- helpful blogposts and stack overflow answers

All these things sum up to lower barriers of entry when trying a new language. Elixir has it in spades. It's really easy to pick up and learn the syntax and predicates of the language (BEAM, OTP, etc.)

Even though Crystal is closer to Ruby in syntax and Ruby can be valid Crystal -- Elixir still feels easier, because there is less work to be done with learning everything else.
