ICYMI | Twitter Is Dead (Really, We Mean It)

The Trump administration wants NASA to land astronauts on the moon by 2027. They also want them to do it with their budget slashed, a leadership carousel and competing views that Mars is more important.  Guest: Joel Achenbach, freelance journalist and author of Moondoggle If you want to support more of this reporting, in 2026 and beyond, consider signing up for Slate Plus.

On today’s episode, host Kate Lindsay is joined by The Atlantic staff writer and host of the Galaxy Brain podcast, Charlie Warzel. Charlie has been following the demise of Twitter, now called X, since Elon Musk took over in 2022. While many of Musk’s decisions have prompted people to declare the end of the app, the introduction of a new location feature undermines almost all of what was left of its relevance. Can we finally call it? Is this Twitter’s official time of death? This podcast is produced by Daisy Rosario, Vic Whitley-Berry, and Kate Lindsay. Learn more about your ad choices.

With so much online content, it can be hard for a meme to stay in the collective consciousness for more than a few days. But one meme this year managed to capture seemingly everyone’s attention - and challenge the definition of a meme altogether.  Guest: Kate Lindsay, host of Slate’s ICYMI podcast.  If you want to support more of this reporting, in 2026 and beyond, consider signing up for Slate Plus.

On today’s episode, host Kate Lindsay is joined by internet culture writer Kat Tenbarge to break down the most important internet moments of 2025. But not just any internet moments—specifically, the moments that fall under the three key themes that emerged in online culture over the past twelve months: brain rot, surveillance, and big tech dystopia. These themes not only defined how we lived life online in 2025, but have set the stage for what to expect in 2026. Were we wrong about the Astronomer CEO debacle? Will TikTok ever get banned? Is 6-7 finally over? This podcast is produced by Vic Whitley-Berry, Daisy Rosario, and Kate Lindsay, with help from AC Valdez. Learn more about your ad choices. Visit megaphone.fm/adchoices

On today’s encore episode, hosts Candice Lim and Kate Lindsay are joined by Slate staff writer Aymann Ismail to discuss the controversial YouTube channel, Jubilee. A video of political commentator Mehdi Hasan debating 20 far-right republicans has gone viral, but as Ismail argues in his piece for Slate, it also crossed a line. When political disagreement becomes content and extremism is rewarded with clicks, everybody loses.  This podcast is produced by Daisy Rosario, Vic Whitley-Berry, Candice Lim, and Kate Lindsay.

On today’s episode, host Kate Lindsay is joined by comedian and writer Youngmi Mayer to talk about a controversy that’s divided TikTok: How should Asian people feel about white people in Asian grocery stores? That’s the question creator Madeline Qi didn’t even mean to ask when she posted her now-viral video, which resulted in call-outs, doxxing, and, ultimately, a conversation too nuanced for TikTok. Youngmi’s attempts to make sense of the discourse on her Substack ended up going viral on Instagram, so she came on the show to share what people misunderstand about the controversy, and how her own experience being mixed white and Asian contributes to her perspective.
