My subscription to this list is via:

Subscribe without receiving mails:

and I read the list via a web browser, not via an
E-mail client. (For example, I've not received your
query via E-mail so far and I read your query in
a web browser.)

This ends up meaning that some of my notes to the list
are from constructing the note from a web page that
I'm viewing. (Like this note.) Other times I've been
TO'd or CC'd and have received it in E-mail as well
and I've happened to reply to that. Thus a mix occurs
