In Germany this was talked already over quite a few years ago.

Wikipedia would have to make it easy to clone parts of its websites to your own service so you can change the parts which are important to you. and then basically the most surfed-on-site wins.

but atm you either fetch the database and set it up with everything.. or .. no idea.

but nobody liked that model either.

we'd need wikipedia with more-git-like backend i think, some guy wrote "levitation" for that, but there would be still a need of setting it up as service and declare which parts are important for you and for which you redirect yourself from your service to the real wikipedia.
