[erlang-questions] Tips on learning Erlang

[Ulises]

Morning all,

I've recently re-discovered Erlang (re-discovered it as I heard about
it in '99 and gave it a go very briefly) and I was wondering if more
experienced people had learning tips such as exercises, sort-of-hidden
documentation, etc.

I've recently read an email where this chap had implemented, as part
of his own learning experience, the smokers problem. So I did too.
That was a nice exercise.

Any other tips then?

Best,

Ulises
