Top-posting

/Top-posting/, sometimes abbreviated as TOFU, used to be an egregious violation of netiquette, but has become more common place in areas which are heavily influenced by MicroSoft software. Prior to the introduction of MicroSoft Exchange most user agents supported proper quoting.

Some may argue that top-posting resulted from the dawn of the Eternal September, but it's current and prolonged popularity can generally be attributed to lazy programmers who couldn't figure out how to do spell-checking with quoted text, resulting in MicroSoft's default formatting.
