bottom-post

v. In a news or mail reply, to put the response to a news or email message
after the quoted content from the parent message. This is correct form, and
until around 2000 was so universal on the Internet that neither the term
bottom-post nor its antonym top-post existed. Hackers consider that the best
practice is actually to excerpt only the relevent portions of the parent
message, then intersperse the poster's response in such a way that each
section of response appears directly after the excerpt it applies to. This
reduces message bulk, keeps thread content in a logical order, and
facilitates reading.
