The world has watched the lives of Ashton Kutcher and Demi Moore unfold on Twitter every day since January 2009. The couple are among the microblogging service's most popular users; Kutcher's @AplusK account has more than 8.3 million followers, while Moore's account, @MrsKutcher, has more than 4.2 million.
Moore publicly announced Thursday that she's divorcing Kutcher, but made no mention on her account.
Kutcher poured some emotion into a tweet: "I will forever cherish the time I spent with Demi," he wrote. The tweet linked to the extended and original version of his statement, posted on social platform Chime.in. That's where you would learn that "marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK."
As when Kim Kardashian and Kris Humphries called it quits earlier this month, Twitter erupted in response to news of the divorce. Some users expressed sadness; others poked fun at the breakup. But few could deny that @APlusk and @MrsKutcher have had a profound impact on Twitter -- as well as their fair share of controversial moments.
The couple married in September 2005, and both joined Twitter in January 2009. Two months later, Kutcher posted a Twitpic photo of a Moore's bikini-clad butt. That picture now has more than 1.3 million views.
In April that year, Moore prevented a Twitter user from committing suicide when she responded to that woman's suicidal tweet.
In 2010, the couple turned to Twitter to tout their campaign to ban child slavery.
For a while, Kutcher was the most-followed Twitter user. He lost that title to Britney Spears in May 2010, and has since fell behind Lady Gaga, Justin Bieber, President Barack Obama, Katy Perry, Kim Kardashian, Shakira, Taylor Swift and Rihanna.
More recently, Kutcher handed over management of his Twitter stream to Katalyst Group, which some people say is a big mistake. It's unknown whether the company approved today's divorce tweet, or whether it also manages his Chime.in account.
Should Moore change her @MrsKutcher handle? Is Chime.in the new Twitter? Let us know your thoughts in the comments.
