Wikipedia, have you met John Seigenthaler?

Wikipedia implemented Monday a registration system for new posts after getting its facts wrong in a bio on Tennessean John Seigenthaler. See story.

Wikipedia's "Seigenthaler saga" raises anew credibility concerns about collaborative writing and peer collaboration. I suppose to some Wikipedia proponents, it proves how self-correcting the process can be. To others, it means the site is wrong until proven right. Seigenthaler, for example, was complaining in the Monday AP story that a corrected version of his bio still got it wrong..

See the Wikipedia entry here.

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

That's a good question.
