Ahh... my apologies for misinterpreting.  I think we agree on this.

Can we explore this a bit?  In two directions:

- My sense is that a lot of the comments in this thread have been about 
the need to promote adoption of Erlang - which is really a 
business/company decision, not that of individual developers (at least 
in my experience, it's companies that make language/platform decisions, 
for business reasons).  It sounds like you and I agree that adoption by 
companies is going along just fine - but I'm not sure that's what others 
are saying.

- It strikes me that the comment that started this branch of discussion 
was something along the lines of "who needs Erlang on a resume?" - or 
words to that effect - which is, as you say, a developer issue.  I 
wonder three things about your assertion that "what's missing is Erlang 
developers:"
-- Is this true?  How does supply and demand for Erlang developers look 
right now?  (Anybody from Erlang consultancies able to comment here?)
-- If yes, is this perhaps a good thing for Erlang developers? (This was 
my earlier assertion.)  Supply, demand, prices, all of that.  20 years 
ago, one could command big bucks for building web sites - these days, 
not so much.
-- Does promotion actually make a difference?  In my experience, there 
are those who are committed to one particular language - doesn't matter 
what language - and nothing is going to get those folks to explore 
another language.  And then there are real engineers, who pick the right 
tool for the job at hand - and my sense that any good engineer who's 
working on high-availability, high-concurrency systems either already 
knows about Erlang, or will find it pretty quickly when doing technology 
assessment for a project with requirements that are best suited for 
Erlang  (mind you "good engineers" are not all that easy to come by, 
particularly when it comes to the kinds of big, complicated systems that 
Erlang is best suited to - but that's a far broader issue than finding 
coders with Erlang skills)
-- On a related note:  A lot of this comes down to computer science 
education.  40 years ago (I'm showing my age), a typical computer 
science curriculum included quite a bit of language design theory, and 
experience with a range of languages (anybody else remember using 
"Structure and Interpretation of Computer Programs" as a 1st-year text?) 
- these days, not so much.  I see an awful lot of people who took a 
couple of courses in Java who think they're computer scientists - but 
ask them about "actors" or "lambda expressions" and you get a glazed 
expressions.  (Real software engineers read lambda-the-ultimate.org ?)
