There is one more paradigm shift possible, it is when authors on the Internet easily reference to Wikipedia when they refer to a subject that is not universally understood. What is a paradigm shift for instance..
It would be a paradigm shift because Wikipedia would be used as a credible source of Neutral point of View information external to the Wikimedia projects. This has huge benefits all way round;
- it provides a shared frame of reference on basic information
- it expands the number of readers of the Wikipedias
- it increases the "google rating" for the webpages that do refer
- the Wikipedias gain a community of people who want to ensure the quality of Wikipedia articles
Organisations like Greenpeace have a rich community of people who know their subjects and as relevant its literatature. This will bolster the quality of the representation of their position in the Wikipedias and questionable sources will become more apparent with increased scrutiny.
Technically the syntax can be something like [[nl:onderwerp ]] or [[ru:предмет]]
