Is 'breaking the thread' a new concept to you?

Sandman
Yep! I don't know how one "breaks" a thread.

No elaboration in this? How does one break a thread? It's an interesting claim from you, Eric. Because in one instance, changing the subject meant I "created a new thread" and in another instance where I did the exact same thing, I "broke the thread". What's the difference, according to you?

Eric Stevens
Apart from your devious detail twiddling, you maintained the subject in general but somehow changed it in detail.

Sandman
"Somehow"? I added a question mark, otherwise the subject was identical. No new meaning, nothing but one single character. Which according to you "breaks" the thread. I am wonder why.

Eric Stevens
You am wonder why. I am wondering at your wonder.

Sandman
And you can't explain it?

Eric Stevens
I can explain 'it' but I can't explain your grammar.

Sandman
I changed the subject twice.

The first time, you said I created a new thread.

The second time, you said I broke the thread.

In what way were they different, Eric?

So, why are they different Eric? Why did I "create a new thread" and "break a thread" using the exact same action? Why can't you answer this question?

Eric Stevens
Because you are trying to prove a point?

Sandman
So, "trying to prove a point" breaks threads? What does that even mean?

Eric Stevens
I can't answer the question because I can't be bothered chasing all over the news group to find the articles you are talking about. Give me a few message IDs or headers and I might be able to help you. But you had better hurry.

Sandman
I'm in no rush.

Here is post #1: <slrnll8p8n.sun.mr@irc.sandman.net> Here is post #2: <slrnllpor2.31b.mr@irc.sandman.net>

Both contains content in the References header, both contain quoted material in the post, and a Message-ID of the post I am responding to.

And both have an edited subject line.

#1 is, according to you, me creating a new thread #2 is, according to you, me "breaking" the thread

Please explain.

Eric Stevens
These primary keys must be unique. 'Subject', 'author', 'date of publication', etc are all secondary keys which need not be unique.

Sandman
Of those three, only one is an actual header field; "Subject".

Eric Stevens
What are all these things then?

Headers, none of which are named "author" or "publication date".

Every post that follows the NNTP standard contains information about the sequence of articles it belongs to - UNLESS it is a new post and thus a new thread.

Eric Stevens
Yes

Sandman
Ah, so now you admit that changing the subject line does not create a new thread. Progress.

Eric Stevens
An article bearing an existing subject line but with no list of references i.e. no list of prior articles can be treated as the begining of a new thread.

Sandman
How about an article that DOES have a list of references, then? Can that post be regarded as part of an OLD thread?

Eric Stevens
For display purposes - yes.

Sandman
So a thread is thus determined by the References header.
