"Erlang in the Real World"

From the top of my head:

- portraits of companies and products who are using erlang

- what does erlang do for them, that is not available in mainstream stacks

- discussing their infrastructure and design desiscions as detailed as possible

- what did they learn

- how are they involved in opensource projects

- numbers and figures of their running systems

This could be a win-win situation. Companies can show their cool stuff. We can learn in what cases Erlang is a good solution.

Anyway - Good luck with your book.
