Hi Eddie.

Fascinating thread.
I think the keys here are courtesy and common sense.
Some exercise them. Some don't.

"each individual poster who creates a thread should be able to conduct their conversation in whatever way they want." - Good one Noel.

I like to reply to each comment individually - I do it because I want to.
I like to comment on the odd song (not all) - if and when I feel like it.
I try not to tell other people what they should be doing.

Cheers.
