The concept here is not so much that people start a new topic and change
the subject, but that sometimes the topic just naturally evolves to the
point that a change in subject is sensible. Take this thread for
example: the topic has drifted from "Clickable hyperlinks" to talking
about email threading. I should be able to change the subject without
breaking the
thread:

Clickable hyperlinks
+- RE: Clickable hyperlinks
│  +- Re: RE: Clickable hyperlinks
│  L- RE: Clickable hyperlinks
│     L- Threading [was Re: Clickable hyperlinks]
│        L- Re: Threading
+- RE: Clickable hyperlinks
L- Re: Clickable hyperlinks


Adding a "Re:" or "RE" to the subject doesn't change the thread, and
neither does changing the subject line in a more substantial way.

Of course, I can always *choose* to sort by subject line, or date.
Personally I hardly ever sort by thread, so it is no skin off my nose
what you do. But when you hit "Reply" to a message, you inherit the
"Reference" and "In-Reply-To" headers from the previous message, so at
least some people will see it threaded in an existing thread rather than
starting a brand new one.

"Cheer up," they said, "things could be worse." So I cheered up, and
sure enough, things got worse.

Interesting history lesson. I actually wouldn't know which came first,
since I've only been online since 1992 (offline computing since 1972). I
do know that I've been on a lot of mailing lists like this one since
1992 (remember Fidonet?), some with actively posting members in the
thousands. And I have never heard anyone whine and complain about
threading issues that had anything to do with the message title until
yesterday. 

So it goes. I'll repeat again that I'll comply with the rules of this
group that are brand spanking new to me, and I've been around a corner
or two.
