The Stanford Encyclopedia of Philosophy[1], while restricted in scope, takes the approach of having experts write the articles that are then revised and evolve with time. So a different approach is possible, but I think it would be hard for an encyclopedia with the breadth of wikipedia to do it. Maybe there is space for more specialised encyclopedias that take the approach of articles having authors and revisions instead of wikis. But all in all, I think both approaches compliment eachother.

Scholarpedia[1] also exists, but is very sparse and mostly a specialist reference.
