Excerpt from this article:
Chinua Achebe, the celebrated Nigerian author of Things Fall Apart, died at the age of 82 in 2013. But to social media, he only passed away this weekend. People began tweeting condolences (or re-condolences) Sunday night, writing “RIP” and “another one gone” and sharing the New York Times obituary from two years ago.
The re-mourning of Achebe spread far enough online to eventually reach high-profile users like the White House national-security advisor Susan Rice, who chimed in Monday morning with her own tweets…
It wasn’t just Rice who missed the fine print—the “news” duped plenty of people. So what happened? As Nieman Lab’s Joshua Benton pointed out, someone likely posted a remembrance of Achebe’s death and recirculated the New York Times obit. Others, seeing the headline and not the timestamp, believed Achebe to have just died, so they fell victim to “reflex sharing” …It wasn’t a hoax, just an Internet-assisted ripple effect.
And that ripple effect happened because social media is, Benton wrote, “unstuck in time,” where old material can be recycled digitally to seem new, where what’s trending no longer means what’s most recent.
…Readers don’t always look at the date and the time of a story, because there’s no association between the story and the time they see it. When in the past, people physically picked up newspapers from their doorsteps at a certain hour during the day (or tuned into TV networks for nightly news), today, the same information is presented to them online not as headlines, but as topics, transformed into key words transformed further into hashtags. The notion of timestamps associated with individual stories can seem, well, outdated.
