Perspective Affinities & Wiki-certified Creden (Score 3, Insightful)

Should we look for new ways to deal with the inevitable vitality of Wikipedia, as a social mechanism to present additional sides of an argument or contentious issue? I'd say there are easy indicators of contention that we'll call 'revisionism,' where the sheer number of edits holds the greatest clue. Perhaps if there were some way to 'diff' the contents of edits / revisions in a summary fashion? It would be cool, for instance, to be able to summarize the changes one party made, and see all "relevant" historical changes on one page. Of course, what is 'relevant' as a summary topic or interpretation of a point, is subjective, but then, could this be user-interpreted, too? What if Wikipedia adopted learning 'preferences' to show a user what they deem to be relevant of issues they have researched on Wikipedia? That would be cool. These interpretation-affinities could be used to score related topics, or to make other suggestions. Some of this is already available, but in my opinion, not where it could be. Also, there are a lot of people who claim to be authoritative when their references are out of scope for Wikipedia. Why don't we provide authority within WikiP's scope, where a reader could judge on any particular poster's credibility based on accessible body of wiki 'precedence'... I'd rather not go all over to determine if s/o is credible as an informer regarding Earth Sciences. I would be glad to have available the highest-level scientific research, it's not really all that complicated if you've got the right attitude.
