The Internet was supposed to provide a utopian virtual world where all of us could come together in peace, love and harmony to better understand each other and our differing viewpoints…

But we got derailed on the road to utopia, didn’t we? Eli Pariser, the man who coined the phrase “filter bubble”, knows as much about this as anyone. I hope you enjoy the conversation as much as I did.

As Hawaii trembles with earthquakes and the Kilauea volcano continues to spew forth lava and gas, residents and the wider world watch and wonder: how long will this renewed activity continue? To find out, we turn to Mike Garcia, professor of geology at the University of Hawaii and funded by the National Science Foundation. He has been following the eruption since its beginning, which actually bubbled to life in 1983. To better understand the history and possible future of Kilauea, I sit down with Garcia on this episode of Miles to Go.

Top US intelligence agencies agree that Russia meddled in the 2016 US Presidential election using an organized campaign of online trolling and misinformation. The details of exactly how are harder to uncover. Jonathan Albright, data journalist and Research Director at Columbia University’s Tow Center for Digital Journalism, studies information flow in networks. Recently, he has been mapping how Russian propaganda spreads on the web. I sit down with Albright on this episode of Miles To Go.

The Cambridge Analytica scandal has placed Mark Zuckerberg and Facebook at the center of the data privacy debate. But is Facebook’s ad-driven business model fundamentally incompatible with protecting users’ personal data? And, if so, what can be done to fix it?

The uncontained engine failure of Southwest flight 1380 reminds us once again that commercial aviation is a business that does not always put safety first - and regulators seem reluctant to change that. Jennifer Riordan’s death could have been avoided if only the FAA did not have a “Tombstone Mentality.” My guest on this special edition: former FAA inspector general and aviation attorney Mary Schiavo.

Long before Facebook, Twitter or even Google existed, the fact checking website Snopes.com was running down the half-truths, misinformation and outright lies that ricochet across the Internet. Today it remains a widely respected clearinghouse of all things factual and not. As part of my series for the PBS NewsHour on the rise and role of misinformation in our democracy, I spoke with Snopes.com managing editor Brooke Binkowski.

Who or what determines what's in your Facebook Newsfeed? It's a complex algorithm that aims to put what interests you most at the top of the queue. Increasingly, Facebook is focused on trying to determine what content is fake, junk or misleading - and sending it to the bottom. But the purveyors of this content are a determined adversary. Miles speaks with their foe at Facebook, the Director of Analytics for the News Feed, Dan Zigmond. It's an interview we did for our upcoming series on "junk news" for the PBS NewsHour.
