Sounds like Drupal or Plone, but cooler. Looked at Plone once many many years ago, but it didn't actually fit my use case, and I can't imagine something like that w/ an opinionated data model ever fitting something I need to make.

But given the popularity of CMS tools, I'm sure it's great for plenty of folks.

I was hoping it was a simple Web framework for me to experiment with Erlang with based on the title here, but alas.

I keep false starting picking up the language, and then walk myself from Erlang to Elixir to Phoenix and just confusing myself. Then I run out of time or interest before I get anywhere.
