 \chapter{Introduction}
 \label{chap:introduction}
 
+In May 2014 \textit{The New Yorker} published a story called ``How a Raccoon Became an Aardvark'' in its column ``Annals of Technology''~\cite{Randall2014}.
+It tells an anecdote about a New York student who, some 6 years before, edited the Wikipedia article on ``coati'' (a member of the racoon family) to state that the coati is ``also known as a Brazilian aardvark''.
+Now, this is exactly how Wikipedia works, right?
+Anyone can edit and small contribution by small contribution the world's largest knowledge base is compiled.
+Except, the kid made the thing up and published on Wikipedia an inside joke he had with his brother on their holiday trip to Brazil.
+Unsourced pieces of information are not supposed to survive long on Wikipedia and he thought that the edit will be swiftly deleted.
+Fast-forward to 2010, not only had the entry on ``coati'' not changed, but it cited a 2010 article by the \textit{Telegraph} as an evidence.
+In the meantime several newspapers and a book published by the University of Chicago~\cite{} claimed that the coati was known as a Brazilan aardvark.
+It proved not trivial to erase the piece from Wikipedia since there all these other sources affirming the statement.
+By then, it was not exactly false either: the coati \emph{was} known as ``Brazilian aardvark'', at least on the Internet.
+
+Now, despite the fact that at any given moment/on the whole Wikipedia may contain more or less the same amount of errors as the encyclopedia Britanica, %TODO quote!
+the stories of hoaxes like the one above are precisely why it is still maintained that information on Wikipedia cannot be trusted and it cannot be used as a serious bibliographic reference.
+
+Quality control.

 Its core developer, Andrew Garrett, known on Wikipedia as User:Werdna, has called it ``abuse filter'', and according to EN Wikipedia's newspaper, The Signpost, its purpose was to ``allow[] all edits to be checked against automatic filters and heuristics, which can be set up to look for patterns of vandalism including page move vandalism and juvenile-type vandalism, as well as common newbie mistakes''.

+As I recently learned, apparently this guideline arose/took such a central position not from the very beginning of the existence of the collaborative encyclopedia.

+To counteract vandalism, a number of automated measures was applied.
+These, however, had also unforseen negative consequences: they drove newcomers away~\cite{HalKitRied2011}(quote literature) (since their edits were often classified as "vandalism", because they were not familiar with guidelines / wiki syntax / etc.)

-If the genesis doesn't make sense here, move it to Edit filters
