Vignettes are short stories, generally with only one post. They very quickly became favoured with the The_Politibrits and many more people joined in. EdT had actually written four vignettes beforehand, but for some reason these did not start mass bandwagonning as the fifth did. Politibrit-authored Vignettes tend to build up to a final reveal (usually concerning the identity of an ATL Prime Minister) but from the outset, writers played with the nascent conventions of the genre, and in most examples the Guess-the-PM format plays second fiddle to more atmospheric and detailed worldbuilding.
