Apologies SGOTI; in commenting on show 4083 I called it a "diatribe", which means a rant or critical writing. I think I was probably going for "discussion" or "discourse" or similar. It wasn't a diatribe I think.

I'm in the phase of life where words sometimes don't pop into my mind when called for, or the wrong one does :-)

Thanks to Ken for pointing it out at the time.
