On Usenet, a posting generated in response to another posting (as opposed to a
reply, which goes by e-mail rather than being broadcast). Followups include the
ID of the parent message in their headers; smart news-readers can use this
information to present Usenet news in "conversation" sequence rather than
order-of-arrival. See thread.
