In a demonstration of the omnipotence of Twitter, what a woman appeared to think was a tweet that would only reach her followers ended up becoming the talk of the internet. Former InterActiveCorp (IAC) PR director Justine Sacco was about to board a plane from London to Cape Town when she tweeted the above. In the course of the 11-hour flight the Twitterverse exploded, with media outlets like Valleywag, Buzzfeed and Huffington Post throwing fuel on the fire by adding their own articles about it. It wasn't long before a new hashtag was created = #HasJustineLandedYet - based on the fact that Sacco was still in-flight and had no idea of the storm her tweet had caused.
When Sacco did eventually land, she was quick to delete every social media account she owned. It wasn't enough, though: in a statement made the following day, IAC announced it had parted ways with Sacco. Sacco finally responded herself, through an apology she issued first to a South African newspaper and then to ABC news. "Words cannot express how sorry I am, and how necessary it is for me to apologize to the people of South Afirca, who I have offended due to a needless and careless tweet."
If this entire saga isn't enough to convince you to tread carefully when it comes to sharing on the internet, then we're not sure what is.
