A founder of the site suggests how — just turn Wikipedia into something it’s not:

But the popular encyclopedia may soon add a new feature that would allow Wikipedia entries to be “cited more comfortably” by students and professors, he said. The feature would allow a version of a Wikipedia article to be frozen and approved by experts.

In other words, many Wikipedia articles would no longer be wikis — no longer immediately updatable. Terrible idea.

The great thing about Wikipedia is that you can use it to get up-to-date facts and citations, and then confirm those citations yourself. You can also use it for background and general knowledge. It serves those purposes perfectly well.

If the creators would like to launch a new site, vetting and moving over certain versions of certain articles, fine, but freezing a wiki that’s not being vandalized just doesn’t make any sense. Besides, would professors make a special exception — you can’t cite Wikipedia, except the “frozen and vetted” articles?
