For a nice example of how articles can gradually deteriorate when the
vandals overwhelm the vandal-fighters, see:
http://en.wikipedia.org/w/index.php?title=Network_topology&curid=41413&…
I particularly love how, after a vandal had replaced a section with the
sentence "The topology system was originally invented by Robbie Cowan",
someone comes along and tags the statement with "citation needed"...
