Wikipedia

In response to the John Seigenthaler fiasco, Wikipedia is introducing a registration requirement for article submissions. But, to quote Seigenthaler and an article (I, II) :

Seigenthaler said he wasn't convinced the new registration requirement would stop the practice of vandals posting content that is slanderous or knowingly incorrect. Wikipedia will either have to fix the problem or will lose whatever credibility it still has, he said.

"The marketplace of ideas ultimately will take care of the problem," Seigenthaler said. "In the meantime, what happens to people like me?"

Exactly. The marketplace will take care of it. There is no way (cost effective way) to guarentee all material submitted is accurate. As for the meantime...see my comments by OnTheMainLine, where Mississippi Fred first posted about this.
