Quietly Using Another Syntax Is What You Get
This term was coined on 2010-12-17 by Jonny Bradley in a conference call with Robert Plummer, Philippe Cloutier, Sylvie Greverend and Marc Laporte, in a discussion about Wiki Parser Revamp, Wiki Syntax, Web-based source code editor and WYSIWYG.
(Maybe it's better as: Quietly Using Another Syntax Istead of What You Get, but then that might be QUASIOWYG, not so pretty - work in progress... jb)
