Does anyone know which major organisations (apart from Ericsson's) are using Erlang in anger? ... Any other telecommunications companies using it? ...
Any organisations in the US? ...

One thing I know for shure: Lucent is not using it. In the past I spent
some efforts to introduce to my colleagues the possibility of using Erlang.
Some of them did like this option indeed, however the management did not
want it. One of the arguments was that our problems were not in the area
of the used language (C and C++). I never fully understood this: Erlang
claims to have 5 times smaller code then C, so it should contain 5 times
less bugs ... but probably I'm naive.

And to think that I thought Lucent was divided in ML and Limbo (or C)
camps... ;-)

Take a look at the program for the Erlang User's
Conference, to be held September 30:
http://www.erlang.se/erlang/sure/main/news/euc99.shtml
There you can read about three non-Ericsson companies
that has been using Erlang in commercial products.

This is similar to my experience. We have seen that the number of
bugs/line is very roughly the same in Erlang as in C/C++. However, the
code volume is much smaller, and thus the total number of bugs is
smaller by roughly the same factor. The same goes for programmer
productivity (roughly the same in man hours/line.)
We have equated this to:
* > 4 times higher programmer productivity
* > 4 times higher program quality
based on actual figures from large projects.
This also gives you:
- shorter time to market
- lower risk by cutting lead times for prototypes
- better risk control by reducing the cost of adjustments and rewrites
We have also seen evidence that Erlang is a much more productive
language than Java for our kind of applications.
Naturally, all this equates to money -- big money. But it's difficult to
prove scientifically that all the above holds.
The naive, but all to common, view is that the choice of programming
language doesn't matter. I've come across this too. The misconception is
that if you run your project right, it doesn't matter what programming
language you choose - or for that matter how good your programmers are.
It's hard to fight this.
I guess people's religion gets in the way. Also, perhaps most big
telecoms companies are still mainly hardware-focused -- software is a
necessary evil, but the hardware is the real product.
But we should just go on fighting the good fight and having fun while
we're at it. It sure feels good doing something you truly believe in
(and seeing practical results that back you up.)

Not naive - realistic.
