Josh, just curious: What are the selling points for learning Erlang? I assume one would be to learn/improve functional programming, but why Erlang in particular?
There are overviews of the language here and here. I recently watched a 2-hour video course about Erlang and tried to solve a few puzzles on exercism.io. I realized that I need to learn more before I do that, so I took the book off of my shelf. 
I’m interested in eventually building things with Phoenix (Elixir) so Erlang knowledge will be useful in the long run, because the languages are related. Someday, I want to build next-generation forum/messaging software. This forum software is nice for some things but it has its own problems. I might attempt it with Phoenix. I backed this Kickstarter hoping that it might be a solution, but the project became inactive.

I found an Erlang video course here:
