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.
