When Wikipedia Fails
PetManimal writes "Frank Ahrens of The Washington Post looks at how Wikipedia stumbles when entries for controversial people are altered by partisan observers. Case in point: Enron's Kenneth Lay, who died of natural causes last week, shortly after being sentenced to prison. His Wikipedia entry was altered repeatedly to include unfounded rumors that he had killed himself, or the stress from his trial had caused the heart attack. From the article: '... Here's the dread fear with Wikipedia: It combines the global reach and authoritative bearing of an Internet encyclopedia with the worst elements of radicalized bloggers. You step into a blog, you know what you're getting. But if you search an encyclopedia, it's fair to expect something else. Actual facts, say. At its worst, Wikipedia is an active deception, a powerful piece of agitprop, not information.'"
Does a group of editors systematically tag all the articles at some point.
There is just too much stuff to do that methodically. 50,000 articles are added every month - just think about how many people would have be there to check them all!
Instead there are a few parallel 'top-down' efforts to make an extra-high-quality core by picking the key articles in every major subject area and flagging the stable versions. One effort is thinking in terms of a printed paper version of Wikipedia - another is looking into doing a CD-ROM version. The articles that make it into these special collections are carefully vetted and tagged - so you know that there is a stable 'known good' version backing up the latest version. However, these barely scratch the surface of the problem.
Additionally, there is a bottom-up process by which article authors can attempt to get their articles recognised for high quality. You first nominate your article for 'peer review' - reviewers monitor this list and come along to check your article. If you pass you can go on to request 'Good Article' status - another round of reviews. Next you can try for the coveted "Featured article" status (there are just over 1000 of these so far) - you get pummeled by English majors and pedants of every stripe - if you pass that then you can try to get your article into 'Article of the Day' - with yet another round of reviews.
Yet another layer is the 'Portal' system. Check out 'Portal:Automobile' for example - it covers the subset of Wikipedia articles about cars. Many portals have their own quality assurance methods and standards enforcement groups.
These quality processes work well - but there just aren't enough reviewers to effectively check the 1.2 million English language articles - let alone all of the ones written in French, Portugese...etc. Remember - English language Wikipedia is growing at a rate faster than any human can read. Nobody will ever be able to read all of it - even if they make it's their life's work.
