[erlang-questions] Convincing industry to use Erlang

As Alain rightly said, Joe you just managed to condense couple of books, and
I'd say a semester's worth of study on Solution Selling and Agile
development. Essentially that's all you need to know. Rest you'd probably

had this been a bulletin-board style discussion forum, I'd have voted for
this to be a sticky !!
