Wikipedia Circles the Wagons

An article by Bobbie Johnson in the Guardian (8/14/09) posits that Wikipedia has maxed out its growth. Research by Ed H Chi, a scientist who works at the Palo Alto Research Center in California, showed that contributions have slowed and the complement of editors has stabilized into a small, elite group. Elite editors' edits have a 1% chance of being reverted, while the work of people who contribute less regularly is likely to be reverted 25% of the time.

According to Johnson, there's a war going on between inclusionists and deletionists, with the deletionists acting to to preserve the value of Wikipedia's content. The inclusionists, on the other hand, point out that Wikipedia is not paper and can accomodate plenty of inclusion.

What's really interesting is the maturation of a revolutionary medium and what it suggests for others. Are there diminishing resources on the Internet, too?
