Stephen Colbert Wikipedia Prank Backfires
Except this is one big MF tribe. A world wide tribe. As I see it, the real problem for wikipedia is the popularity of authoring. The more popular it becomes to write for wikipedia, the more difficult it will be to maintain quality entries.
This is a self correcting cycle as spammers, and propagandists find that they can not have their way with the content, readers find that the content is too biased/low quality, authors find that they can not get good content up without endless battles.
I believe that in the end, wikipedia will be a great source of information for topics that are not popular, controversial, or prone to be targeted by marketers. Basically, stuff that matters.
