Okay, if you're going to be smart-arsed about it, there were two sends 
-- I couldn't remember whether I'd used a send from Bus 1 to Bus 2 or 
just hooked the output of Bus 1 directly to the input of Bus 2, in 
addition to the send from Bus 2 to Bus 1 which closed a loop.

Okay, the end effect can be the same, but with a Send the level can be 
varied so that the feedback is controllable or runaway. If you connect 
inputs to outputs it could get very nasty very quickly I imagine, unless 
you happen to pull one of the faders right down beforehand. But with 
sends being created at -inf the feedback loop won't do anything until 
you raise the fader on the send (assuming the other send fader has also 
previously been raised).

But ultimately, I don't know, why is the send special? YOU'RE the one 
who picked up on that in Axel's post then responded to mine.

I guess you might be trying to say in a cryptic way that Ardour can't 
tell one send from another and that all sends have a fader. Or that it 
can, in some instances, take two sends to create a feedback loop. So what?

The point was, I created the loop DELIBERATELY, BY DESIGN, ON PURPOSE 
and Ardour let me use it until the next time I opened the session.

I can see that, in some cases, feedback loops could be a problem. But 
not necessarily in all and between various fader settings feedback can 
be controlled.
