In a world that is moving to greater transparency,
wikipedia is, in
fact, a model. Consider being able to earn one's degree by writing on
wikipedia.
But if you accidentally find out something that wasn't known before
you'd have to erase it from Wikipedia and move it somewhere else... :/
Which also implies you could never earn a PhD by writing on Wikipedia.
I hope Wikiresearch and/or Wikiversity will become a bit bigger to
tackle this inconvenience. :)
