With all its problems I think it's one of the most utopian movements out there, giving free knowledge to everyone on the planet. I don't understand why it's so absent in the popular culture.
@alxd Doctorow's _Walkaway_ has a society built around a wiki.
Not wikipedia, that's a pretty global singleton top-down, heavyweight, ossified structure for solarpunk. ;-)
@alxd but the book has a line about "I should revert your reverts" which is as wikipedia as it gets.
@alxd New Model Army by Adam Roberts comes to mind. It involves an army run by wiki, though I don't recall if it specifically references Wikipedia.
It's briefly but strongly mentioned in the (great) Robert Sawyer WWW series https://www.goodreads.com/series/46141-www - I wish I knew of more. -- The list here (and more in the navbox) might contain more, but I don't think they've been kept updated in many years. https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_in_books
