"Wikiality," from populist Online encyclopedia, Wikipedia, means reality as determined by majority vote (as when scientists voted to stop treating Pluto as a planet).

Are you wikiliterate? If not, start studying!

For one thing, "wikiality," a Stephen Colbert-inspired "word of the year," is a password that signals you are an irony insider. But beyond that, the wiki website model, popularized by Wikipedia, is also emerging as a hot business tool.

Any user can change any entry and if enough other users agree with them, it becomes true. ... If only the entire body of human knowledge worked this way. And it can, thanks to tonight's 'Word': Wikiality. Now I'm no fan of reality, and I'm no fan of encyclopedias. I've said it before: Who is Britannica to tell me that George Washington had slaves? If I want to say he didn't, that's my right. And now, thanks to Wikipedia, it's also a fact. We should apply these principles to all information. All we need to do is convince a majority of people that some factoid is true.
