Just a few years ago, it seemed nearly everyone, in academe and out, was hailing the wiki as the next great transformative technology — or, at the very least, a tool worth getting a bit excited about. Fast forward to 2009, though, and much of the enthusiastic talk has died down.

So says Renay San Miguel in an article for Linux Insider, and he’s got something of a point. Wikipedia aside, there really aren’t many heavily hyped wiki projects, and social-networking tools like Facebook and Twitter seem to have stolen the spotlight. So Mr. San Miguel wants to know: “Have wikis lost their mojo?”

It’s worth noting that plenty of wiki-friendly concepts and innovations...

Microsoft has announced that it will soon euthanize Encarta, the onetime encyclopedia-of-the-future that has lost much of its luster in the last decade. But the company really didn’t have much choice in the matter: For all intents and purposes, Wikipedia had fatally shivved Encarta some time ago.

And Microsoft admits that. In recent years, “the category of traditional encyclopedias and reference material has changed,” the company said in a statement on the shutdown. “People today seek and consume information in considerably different ways than in years past.” So there’s really only one question left to be answered: Should Encarta be mourned?

Christopher Dawson of ZDNet certainly doesn’t think so. The demise of...

By now, if you’re even moderately interested in Wikipedia, you’ve probably had the chance to read any number of lengthy articles on the Web site’s meteoric rise. So why bother with a whole book on the topic? In the case of Andrew Lih’s new tome, The Wikipedia Revolution, the answer is simple: The author is a longtime site administrator, and he has enough pull in the community to get Jimmy Wales, Wikipedia’s founder, to write a foreword. So, for all intents and purposes, this is Wikipedia: The Authorized...

Need a gift for that open-source enthusiast in your life who happens to have some bookshelf space to fill? A German company called PediaPress has come to the rescue: For a not-unreasonable fee, it will create a book that compiles your favorite Wikipedia articles.

PediaPress has been at this since January, when it started printing volumes drawn from Wikipedia’s German-language edition, but late last month it added to its repertoire six new languages: French, Polish, Dutch, Portuguese, Spanish, and Simple English (from a version of the encyclopedia written for children and for adults learning English as a second language). Regular English is on its way soon. It’s taking longer to work out the kinks, though, since that encyclopedia is so massive.

Assembling a book is pretty easy: Wikipedia has set up

When Jeremy Boggs, a graduate student in history at George Mason University, stepped away from American Idol to look up Langston Hughes’s Wikipedia page Tuesday night, he could scarcely have imagined that he’d end up helping to inform police about a threatened school shooting in St. Louis. Then again, the Internet can be a strange place, as an article in the St. Louis Post-Dispatch points out.

The Post-Dispatch has a complete blow-by-blow of Mr. Boggs’s unusual evening, but here’s the quick version: The page on Langston Hughes, it turned out, included a strange and threatening piece of vandalism (“I GO TO LIFT FOR LIFE ACADEMY… I’M GOING TO SHOOT...

The rise of Wikipedia seems to have afflicted some scholars with a mild case of existential panic. And understandably so: When the world’s most popular reference tool is such an egalitarian outfit, that can be interpreted as a fairly stiff challenge to the value of expertise, right?

It most certainly can, writes Larry Sanger in a new article on “The Fate of Expertise After Wikipedia.” But fear not, scholars: Expertise, he says, will win out in the end.

Seasoned Wikipedia watchers are already familiar with the saga of Mr. Sanger: He was there with Jimmy Wales when the online encyclopedia was founded (and, in fact, when its predecessor, Nupedia, was conceived), but he left Wikipedia in 2002 because he felt the...
