Is this actually desired, though? Sometimes it will be -- a correspondent may wish to take one throwaway line and effectively start a new topic based on that concept. In such a case, a new thread might be the Right Thing. But usually, a topic will drift over a number of posts. My experience is that on most forums the subject will drift and only some time later someone will think to change the subject line. In this case, deliberately breaking the thread is *not* what is wanted, since it will separate the drifted topic into two threads -- the original drifted messages and other responses, and the split topic with the new title. Usually these will sort some way apart in the subject list, readers will not be aware of the other thread, and you will end up with related branches of the same conversation in multiple places. This is usually what the users of threaded e-mail clients *explicitly* wish to avoid. Perhaps you would like correspondents to post one short message in the old thread pointing readers to a new separate thread for the diverged topic. I have not found this to be accepted practice on mailing lists or Usenet. Others may feel that simply changing the name of the thread later (so at least readers can identify that these posts are not on the original topic and ignore them if they wish) is easier.
