With Twitter apparently on the verge of falling into the hands of billionaire troll Elon Musk (or maybe not), I thought back to a time when we thought it could be used as a force for good. More specifically, I thought back to a story broadcast on the “PBS NewsHour” 11 years ago (above) in which Andy Carvin, then with NPR, talked about how he was using it to track the Arab Spring uprisings that engulfed Tunisia and, later, Egypt and beyond.

This is a great story, and I hope you’ll take a few minutes to watch it. I used to show it to my students as a demonstration of how Twitter could be used to track news in real time. If I showed it to them now, it would be as a historical artifact.

Carvin began with about a half dozen people in the Middle East who he was already following on Twitter — what interviewer Hari Sreenivasan called Carvin’s “first ring of trust.” From there, Carvin looked at who those people were following. He’d engage in private conversations via DM to add to his circle, building a “mental map” and explaining: “It doesn’t mean that they’re all reliable. It does mean that they’re all talking to each other.”

Carvin also discussed his methods, some of which I would not recommend today given the toxic cesspool that Twitter has become. “I see my Twitter feed as an open newsgathering operation,” he said, explaining he would often retweet items with comments such as “Source?” or “Verified?”

In one such instance, he said he retweeted a sign being held by protesters in Iran that showed three prominent politicians photoshopped to make it appear they were about to be hanged. He was able to verify that the sign was real. Today, given that Twitter has long since grown beyond a small conversation among a fairly sophisticated community, that sort of activity would be called out for promoting misinformation and probably removed by Twitter. (But maybe not after Musk takes over.)

Carvin talked about what was then the surreal experience, now fairly common, of watching live coverage of the protests in Egypt’s Tahrir Square while using Twitter to follow people on the ground. “You don’t necessarily get complete situational awareness,” he said. “But you get a pretty close proximity to it.” Just a few years later, in 2014, many of us followed the birth of the Black Lives Matter movement on Twitter as protests broke out in Ferguson, Missouri, after the police killing of Michael Brown — protests that television didn’t catch up with for many hours.

Carvin also discussed the overwhelming nature of social media, saying he would check tweets on his phone while making dinner, lay off while eating with his family and reading to his kids, and then go back to TweetDeck until nearly midnight to keep up with the latest. Of course, Carvin was a journalist covering vitally important live events, and his routine was certainly less exhausting than being a reporter on the scene. If you leave that aside, though, it speaks to the difficulty we’ve all had of achieving any sort of work-life balance in the age of always-on digital technology.

“I don’t know how to juggle all this,” he said. “I’m kind of hoping that others will be able to come in and do similar things. I probably will reach some saturation point at some point. I’m not there yet, but I’m getting pretty close.”

Twitter remains a valuable tool for journalists, but it’s fallen far short of its initial promise. It’s hard to see how Musk is going to make it better. Even after reaching a deal to buy the platform, he was attacking top executives at Twitter, unleashing his army of trolls. It has not been a good week — or, as the Carvin video reminds us — a good decade for any of us who are interested in preserving some sliver of civil online discourse.
