from Kay contains these words:

Just as a matter of curiosity - why did you start a new thread for your
response?

Must be an idiosyncrasy of Turncoat - all the posts have arrived in the
same thread here.

It's probably down to how the different readers determine if something
is in a thread.

Turnpike uses the references header to work out the threading of
messages rather than the subject line. This means if someone starts a
new thread with the same subject title it will put these messages in the
a new thread as the message won't have nay references in the header.

Problem with relying on subject for threading is that if someone starts
a new thread with the same name as an existing one then the messages
from the new thread might get put in with the old one (Google groups
does - or maybe now did this ISTR)

Of course the OP was posting via Gardenbanter so who nows what might
happen :-)
