The Poll Confounds  the  delevery vehical and  content  when   suggesting that  Wiki's vs Documentation  is  source of confusion.

Wiki's are a delevery  stream  while documentation is content in the stream.  As to Wiki's contribution to confusion of documentation is  more a statement as to the process and not the content.  Wiki's are are more likely  to generate confusion as they usually lack documentation processes or controll... akin to  creating a giant white  board  for  teams to  throw up  dynamic verbage.  Content and document control  as well as wiki process control of  distributed "Documentation" are needed to  contain confusion , duplication, and or inaccurate content.
