Well, without further qualification, and especially given to someone new
to Erlang, I think such a statement is rather misleading - it makes it
sound like Erlang would be prone to randomly dropping messages, like,
say, UDP. This is not the case, of course - if the recipient process
keeps running, the network (if needed) remains up, etc, every message
sent will also be received by the recipient (and there are mechanisms
available to make sure you get notified if one of the "bad" things that
might prevent this happens). See also:
