I see a serios problem with a number of the examples on the playing with pages. On tropes used over a long peroid of time, as opposed to just as a one time thing, the zigzagged example is just, "used sometimes, sometimes not used. That seems more like inconsistant than zigzagged.
Anyone mention the good old joke-form:
"Good-news / Bad-news / good-News / bad-News ..." ???
Do i need an example? Naaahhh... - surely not...
