I'll return to that page and read it again. Perhaps in the context of my
question I'll gain exactly what I should from it -

In some circumstances, I know of course that these things are not
interchangeable. And there clearly are circumstances where it's easy to
show how and why they are not interchangeable. In my case, I may not
need to pursue this further today because my goal, at the moment,, is
only to open a connection to a jabber server so that an extremely simple
client can respond to incoming messages. At this point, the quality of
the response isn't important, just that the response mechanism is at
least working.

But at that later point, which probably isn't all that far in the
future, I'm sure that a better understanding of "interchangeable .... or
not ...." will be very, very useful. Which is to say if you can point me
to a few more good (and very simple) examples, I can probably go from
there. David's example, in my opinion, is an excellent starting place -

Thanks in advance,

Perhaps since I asked the question, I'm the one who should answer it :)
