Edit everything?

Some interesting news in yesterday's Telegraph regarding the decision by Encyclopaedia Britannica to finally allow readers to edit it's online content. Is the resource a Wikipedia-wannabe or just improving its "symbiotic relationship between editor and reader"?

At the same time, the RNA Biology journal is apparently now requiring academics to post their research findings on Wikipedia. "Modification activity", as Terry Wassall puts it, is obviously a concern but it certainly supports the idea that distinctions between subscription and non-subscription resources are blurring.
