Wikipedia should make this information available generally. If someone wants to post information for the general public, we should know who they are.

Once Wikipedia provides the game for everyone to play, they should also clarify the rules and keep it "clean" and accurate. It's a good idea to collect resources this way but to make it perfect is another task to do.

Although the invention is good and it's good to know who edited what, but from now on, those who really want to edit or doctor postings on Wikipedia, would do so from home or public computers, such as Internet cafe or public library etc. Don't you think?

This is a non-story. Wikipedia can already do everything that this grad student's site can do. Mediawiki recently (a few months ago) added the ability to display the edits for a RANGE of IP addresses, which is the primary feature of this guy's interface. I'm not sure if the feature has been enabled yet on en.wikipedia.org, but the point is that this NPR story makes this guy sound like a genius when he's simply reinvented the wheel.

The only story is that people have suddenly noticed this option and started looking for immoral edits.

I'm an enthusiastic Wikipedia user and some-time contributor. I think we wiki-heads have always known that entries are subject to vandalism and self-interested modification. We accept the risk because we also know that, because of its open characteristics, it's a repository of information we'd not have access to anywhere else.

Do we double check Wikipedia entries? Certainly; Wikipedia itself encourages footnotes, annotation, and links to other sources.

I've always double checked all sources of information, including print encyclopedias. Who writes and edits the entries in Encyclopedia Britannica? Why are they necessarily more expert than the academic down the block? What are their political affiliations? What's more, inaccuracies and unfounded opinion live on in book-form indefinitely.

Wikipedia is edited in real-time by thousands; sometimes the edits are beneficial, sometimes they're not. They are as subject to change as understanding and perceived truth themselves are subject to change.

The spin on companies editing their Wikipedia pages was unneccessarily negative. A smart company absolutely SHOULD be involved in anything that impact the public's impression of their firm. The bottom line is that companies shouldn't lie; they shouldn't overstate earnings and things like that, and this tool will be useful to smoke this out. But, a company shouldn't let Joe Schmoe decide who the company is either. If a company is transparent and responsible in their involvement in Wikipedia, then I don't see this as a problem. A company has just as much right to edit a Wikipedia blog as an individual -- they just need to be careful of how this involvement will be perceived by the public and, in turn, how it will impact its public image.

Great interview. My one complaint is that the discussion made it seem like these malicious or mischievous edits were only discovered with this tool, and that anyone reading any of those entries is likely to be the victim of a spinjob or silly prank.

Virtually all the biased edits discovered through WikiScanner were reversed soon after they were made. It takes a lot more sophistication and subtlety than what most of anonymous editors did to actually create a lasting spin in a Wikipedia article.

That said, there are some companies and other parties whom many Wikipedians do suspect of more systematic and sustained attempts at Wikipedia PR management. The more people are aware of how Wikipedia works and the risks that go with trusting it blindly, the better.

I've got to agree with some of the other commenters. This isn't exactly breaking news - it's always been possible to track down the IP address of people editing Wikipedia. This new tool automates the process, sure, but plenty of Wikipedians have taken it upon themselves to examine the IP addresses of edits that seem suspect as part of their routine duties. People and entities editing Wikipedia anonymously get busted all the time. The tool just makes it easier.

One thing that's somewhat misleading about the WikiScanner tool is that it doesn't tell you how long it took for the edits to be fixed by someone else. On a lot of entries, particularly controversial ones, new edits are checked constantly. So while Wikiscanner may show that a particular entity made an edit to a page, often the edit doesn't survive very long before it's scrutinized by other wikipedians.

Did you check to see whether the changes you talked about were kept or whether they were undone? Did you talk to anyone who edits wikipedia? Basically, it would have been nice to see some actual reporting.

I looked up NPR's IP addresses using a WHOIS search, and found a few edits which might bear some additional scrutiny. It looks like NPR's internet access is through 205.153.36.170 and 205.153.36.171.

I wonder who did the major edit on Nina Totenberg's bio on May 14th? Or Jackie Northam's on April 30th?

I was amused to find a quote on the "Tor" anonymizing service website stating that NPR foreign correspondents use that service to post stories while they are in locations with internet restrictions. Perhaps they should teach the home team a few tricks?

Wikipedia has always had an open policy, they've never hidden the info about who's making what edits- they just don't track or automate the info. This guy from Cal tech did us all a favor by creating this program. I've followed IP's of posters who have disrupted my blogs and boards and found them editing wikipedia entries and generally making a nuisance of themselves there as well. This easier access will be beautiful for me personally as I like to double check my sources as often as I can, and I always like to know what my cyber stalkers are up to. Love it!
