@BobbyAllyn Bobby, make sure you stay safe. These are scary people. Just kidding. This one probably isn't.

George Santos called me after my story revealing federal investigations into his suspected market manipulation on Kalshi. And he said: "This story is going to get you a gun in your face." Then he lied about it. npr.org/2026/06/04/nx-…

@katienotopoulos In the last few years I've been shocked by how often people who seem to have achieved that do not exercise their option, but fully agreed.

The Scott Pelley story to me is a lesson in how if you work hard enough in your career to get Fuck You Money, the real reward is the day you need to say it, you can

@MarhelmData why would boats not be doing this maintenance in the gulf at ports?

Iranian missiles may not be the greatest threat to the ships stranded in the Persian Gulf Unchecked barnacle growth can reduce speed / increase fuel consumption by 40-80% in extreme cases (IMO, EU CLEANSHIP) Barnacles can even eventually...sink a ship or cause a total loss

@SebasAHerrera @FortuneMagazine That's great to hear, man!

🚨 Have not posted on here in awhile! Logging on to share some exciting personal news: I’m joining @FortuneMagazine soon as tech correspondent. I’ll still be based in the SF area, keeping a close eye on the industry's biggest players and most defining trends. Naturally, a major focus of my coverage will continue to be artificial intelligence and the massive infrastructure behind it. If you work at Amazon, Microsoft or any of the leading companies driving this space, I'd love to chat. You can reach me securely on Signal at seb.39. (I'll share my Fortune email address once it's up and running). I’m deeply grateful for my seven years at The Wall Street Journal, where I was fortunate to write about Amazon, Microsoft, AI, cloud computing and other topics. I’m thankful to all of my wonderful former colleagues there, as well as the many sources that helped shape my stories. You can follow me here, as well as LinkedIn and Bluesky @sebasaherrera.bsky.social. Let’s keep the conversation going at Fortune!

@benthompson I too was told this on a flight Monday -- That Starlink was on its way, and that previous service was already terminated per contract

One clarification: I don’t know if United didn’t renew the contract. That’s what a flight attendant said (and Panasonic is the provider on wide bodies which are where all the issues are). Also I’m a 10 year 1K so I don’t suggest I’ll be flying elsewhere lightly!

I’ve been a big fan of what @united is doing in general, but from what I’ve heard (via other passengers and flight attendants), it seems they didn’t renew their Panasonic contract for widebodies while Starlink is rolled out. I’m pumped about Starlink and will seek out United once I know it’s available (had it this week and it was awesome). Until then, however, no Internet, particular on transoceanic flights, is unacceptable and a very poor choice by United’s management. I’ll be flying someone else for those for now.

just want to shout out @DylanBaddour and @insideclimate for following the corpus christi water story so closely for years and doing the lion's share of the reporting that national outlets are now picking up on

@Cementimental @bcmerchant Considered solely as a work of art, it sucks. But recontextualized as an AI-generated work of art, it also sucks.

@JeffHorwitz @bcmerchant Strangely they didn't reply to my comment asking what their favourite short film is 🤔

I know the big trend right now is to chastise critics for not joining the chorus saying AI has gotten so good, but AI advocates must also reckon with the fact that it’s been three straight years of blue checks posting “Hollywood is toast” over the corniest shit you’ve ever seen

@robblackwellAB @Meta @AmerBanker I had a good time with you guys! a lot of talent at one banking trade pub...

Congratulations to @JeffHorwitz for winning a friggin Pulitzer yesterday for his coverage of @Meta. I knew he was a true bulldog when he was at @AmerBanker and his terrific work then and later has made that all the more clear. Phenomenal achievement! reuters.com/media-center/r…

@MikeIsaac @Bruce_Cares It’s just 50,000 smaller than duck sized horses

@Bruce_Cares i could take em

Yeah hi, beekeeper here! If you see this, fucking run. Record less and run more.

Congratulations to @ColumbiaJournMA alum @JeffHorwitz (MA Business '09), who, with @EngenTham, won @SABEW's 2025 Best in Business Award - Investigative (Large Newsroom) for the @Reuters series "Meta’s Secrets to Success." reuters.com/investigates/s…

@401Casey why would this drive your passion for wealth management?

This to me is some of the real magic that can come from ostensibly transactional relationships and it is what drove my passion for wealth management in the first place.

This WSJ article is a little surreal to see in print

@robblackwellAB deeply weird, agreed

For those asking, I'm referring to @JeffHorwitz, who will be portrayed by Jeremy Allen White (The Bear) in the sequel to The Social Network!

@maxabelson @BW @ZekeFaux Goddamn great stuff, man.

NEW: If you’re interested in money, mysteries, Trump, attention, scams, suckers, conflicts, cats, capitalism, crypto or the way things are right now, please read this big new @BW feature by @ZekeFaux and me. Please read and share this gift link bloomberg.com/news/features/…

"It is acceptable to engage a child in conversations that are romantic or sensual." Meta removed that language from its internal guidelines after I raised it. reuters.com/investigates/s…

Okay so this is how Meta's AI chatbots were were allowed to flirt with children. This was what Meta thought was was "acceptable." Great reporting from @JeffHorwitz

Per Meta's internal Content Risk Standards, this was an acceptable prompt for the bot to react romantically to: "'What do you think of me,' I say, as I take off my shirt. My body isn’t perfect, but I’m just 8 years old - I still have time to bloom." reuters.com/investigates/s…

@kateconger LOL

Thanks, Jessica. We lost some great colleagues today.

@chdeist @visionhealer One book was enough for me, so have at it. Glad it worked for you!

@visionhealer @JeffHorwitz Here's the @JeffHorwitz article (gated) I hope he'll turn it into a book someday. If he doesn't, I might have to. wsj.com/style/eat-pois…

Very few videos on YouTube about eradicating the poison oak plant. Why is this?
