Erlang does have problems

If this is really THE problem for Erlang systems, I think Erlang
should be extended with a native String type. It would have similar
functions to lists, but be more efficient. It really doesn't sound
like such an insurmountable issue to me, but maybe I'm understimating
what it would take.

I know that Meebo, jabber.org, and Gizmo project all use Ejabberd and
as far as I know they are happy with it. These are all very big
deployments.

Erlang doesn't have to become mainstream. It just has to make OUR
lives easier. That's my take on it, anyway :)

Best,
