"To be honest, I was very surprised at the traffic we got," the confessional (titled "The Psychology of an Internet Hoax") read. "Twitter is like a pinball game when it comes to spreading the word. Your ball bounces around and just when you think it's almost out of a gas, it hits something that shoots your ball back into the heart of the game with renewed energy. ... It's like every so often your Tweet drinks a Red Bull and goes hyper all over again."
And then there are the celebrity deaths. In July 2009, as news of Michael Jackson's death started overtaking the Web, a blog post claimed actor Jeff Goldblum had been killed on the set of a movie he was filming in New Zealand.
So many people believed the report that his spokesperson had to release a statement to the media debunking the rumor.
"Reports that Jeff Goldblum has passed away are completely untrue," read a statement issued by the actor's publicist, Lisa Kasteler. "He is fine and in Los Angeles."
Similar statements debunking claims of death were published on Twitter about Goldblum by his actor friends, including Kevin Spacey.
Throughout the summer, false reports of celeb deaths continued to populate Twitter streams and blog pages. And in October, reports of rapper Kanye West's "death" reached such a pitch that "RIP Kanye West" became the number one trending topic on Twitter.
Some Web sites said Kanye had died in a car crash, while others said the artist had killed himself. The rumor was false but ostensibly still inspired the Web site KanyeWestIsNotDead.com.
"Why?," asks the site of itself on the "About" page. "Great question. To let you know that Kanye West is not dead."
Some hoaxes are more persistent than others.
At least a couple of time last year, messages spread across Twitter and Facebook pretending to be AMBER Alerts about kidnapped children.
In October, a tweet gained considerable traction about a kidnapped 3-year-old boy. It said the boy had kidnapped in a Mitsubishi Eclipse and provided a license plate number.
According to Mashable, computer security company Sophos said it was a hoax. But it was so successful, the license plate number placed among the top trending Google terms.
(In the future, the site warns that National Center for Missing and Exploited Children's Web site is a good place to go to verify these kinds of messages.
In May, the Los Angeles Times ultimately tweeted a Web 2.0 retraction when an old story about California's Proposition 8 took on a life of its own on Twitter.
Thousands of people retweeted a message that the state ballot measure restricting same-sex marriage had been overturned when it really hadn't been.
Someone unearthed an old article in the Times about gay marriage ban being overturned and retweeted the link to the 2008 article.
"This incident highlights a downside of Twitter," blog TechCrunch wrote at the time. "While it's great at disseminating information quickly, it's just as good at disseminating false information quickly. And if a lot of people are saying it -- as thousands are here -- it must be true, right? Wrong."
