- Reposted by Leon YinNEW: For months, my colleagues and I dug into YouTube's conservative airwaves and found a flourishing network of host-read ads on right-leaning podcasts. This phenomenon has enriched hosts, YouTube, and businesses that use ideology to sell. bloom.bg/3Kaio9w
- Reposted by Leon YinFriday was my last day at WIRED. Today I started a new job at Bloomberg on a dream desk with @suryamattu.com and @jeffykao.bsky.social. Got a tip? A dataset? Something we should look at? Find me on Signal at dmehro.89 In no particular order, here’s some stuff I’d like to continue to dig in to:
- Headed to New Orleans or my first @ire.org Conference. I'll be on a panel Friday morning (11:30) on crowdsourcing data for your next investigation w/ Cassandra Garibay and Sergio Olmos. schedules.ire.org/ire-2025/ind...
- Good "missing data" story
- When Trump encounters a demographic he doesn’t care for, he “disappears” them–in many cases, the very record of their existence. Meet America’s new “missing persons," and the govt campaign to delete statistical evidence of anyone who doesn't fit Trump’s idea of our new golden age. w/ @ashendruk.com
- Tried "vibe coding" ... hated it! ¯\_(ツ)_/¯
- Reposted by Leon YinNEW: The US government has collected DNA samples from 133,000+ migrant children and teenagers and uploaded them into CODIS, a national criminal database originally built for convicted sex offenders and violent criminals, according to documents reviewed by WIRED.
- Reposted by Leon YinThis is a great story, the kind of great story you can do through using the data released by The Deportation Data Project: deportationdata.org Every data reporter covering immigration should get familiar with the data here
- NEW: @bloomberg.com analysis of +13 years of ICE detentions shows immigrants transferred to the South and SW from interior US at unprecedented rates. Reducing the odds of winning their cases. w/ @elenamejia.bsky.social @racheladhe.bsky.social @pollymosendz.bsky.social bloom.bg/43am95w

- Getting transferred to the South and SW reduce detained immigrants' chances at staying in the country. 70% of people detained in Louisiana and New Mexico end up deported, which is double that of the Northeast and the Nat'l Avg, which is about 50%. bloom.bg/43am95w
- In prior years few immigrants detained by ICE in the Northeast were sent to the South & SW. Virtually nobody sent to New Mexico, and less than 1% of ppl sent to Texas or Arizona. In Trump's first month, 12% of ppl detained in the NE were sent to Texas, 4% to NM and 3% to AZ. bloom.bg/43am95w

- After a big story we (reporters) go back to zero. It's a lifeless and cold wasteland. Sometimes we shine a light down a new rabbit hole and see new potential to start digging again.
