"The culture on X today is remarkably friendly and inclusive. It is a cheerful place", I couldn't agree with @daringfireball more. X is the place to be if you genuinely like technology and progress. Just such a delightful optimism here. https://daringfireball.net/2026/10/x_once_again_marks_the_spot

I discovered that 1000s of bots are actively monitoring X for new links posted, probably not just on my account I noticed when everytime I'd share one of my sites new features or pages, the page would get a bit slower just after posting, then I asked Claude to analyze it I tweeted a test URL as a reply somewhere deeply hidden in a thread (so not even a main post) And within 8 seconds there's thousands of crawlers opening the page! One is a military intelligence firm, that scans social media for breaking news and sells alerts to newsrooms, banks, companies and government, it specifically follows accounts with many followers Another one is a social media monitoring company that tracks what people say online I knew of course high frequency trading firms use online news to trade fast on things, but interesting to see it in real life Twitterbot (X) of course is first, within 0 seconds of sharing, it opens it (probably when I wrote the tweet) The first non-X bot arrives just 8.40s later, which I think is pretty fast considering it's a reply by me deeply hidden in a thread somewhere TL;DR they're watching you!
@levelsio

@mvanhorn
Grok Bot doesn’t need the X connector/API credits to search through X anymore!!!! this is actually insane
@kr0der
you know this feeling when you see everyone doing amazing things, and it just drains all your energy as you feel so behind well, today I did a customer interview I showed a new feature, she was blown away people on X are like "meh" real people out there are blown away it refueled my energy 200%, and I now want to ship 10x X is a bubble, remember to get out from time to time and remember 👉 talk more to real people
@tibo_maker
Figma doesn’t want you to use MCP Amazon doesn’t want you to shop with agents Reddit won’t let Claude access threads X won’t let ChatGPT read tweets It’s starting. This happened with APIs 8 years ago.
@wesbos
Bot detection & human verification will be one of the most urgent demands for businesses over the coming years. Agent swarms will suffocate every website and form; small companies and government websites are most vulnerable. There is a huge gap in the market for this right now. When we looked at what offerings were in the market to use at X, there was not a single company that brought together all the latest technologies so we had to do it all in-house.
@nikitabier
Here's how I run my software factory: 1. During the week, I collect ideas + inspo. 2. On the weekend, I give the list to an agent to rank the best ones. 3. I spin up ~5-10 parallel agents to build POCs. 4. I kill ~60%, iterate on the better ones, and end up with 2-3 solid demos. 5. I then polish & share those demos on X. Then rinse and repeat! I still build some ideas immediately, but I'm increasingly using weekends to let agents explore ideas in parallel.
@nutlope
TL;DR of my new article: the 9 Instinct prompts people are actually running. Instinct is three weeks old and invite-only, and The Information says it is already in talks to raise another $1B at a $10B valuation, two weeks after being valued at $2.5B. The public argument about it is a privacy fight. Meanwhile the people who actually have it are quietly using it to find money. I ran @slashlast30days on it eight times, then six direct X sweeps, and pulled the 9 prompts worth stealing. 💰 The unclaimed-property sweep. @peterpham's tip got him $845. My tightened version got $2,182.72 across 5 properties, found my SSN proof, and signed the forms off a passport photo. Then @morganb ran my exact wording and posted $2,222.57 🧾 @EliLanger's Amazon back-refund audit: a numbered checklist across your ENTIRE order history, not just recent orders. His run took 5 hours over 16 years of purchases. Check the refund card is still active first ✈️ Track the fare after you already bought it and chase the airline for the difference (@DavidPawlan). It tracked fine, then needed a human for the actual call 🔭 Monitor-and-book as a standing order. @VoyageBliss connected secondary frequent-flyer accounts instead of his primary, and scoped a read-only token for everything else. Read-only, single purpose, revocable 📸 Screenshots plus "can you do this for me". Six words got a soccer registration form filled, a password reset, and a birth certificate pulled out of an old email ☎️ Bill negotiation with a hand-back. @pitdesi went $100 to $60 on Comcast. When it hit a wall it handed him the number AND the exact script. The call took 3 minutes 📬 Forward the email instead of connecting the inbox. Your Instinct got its own address on Sept 8, so you can hand it one thread instead of your whole account 🔍 "Show me your activity log." @jbahrdestefano got banned by Resy, asked his bot what it had been doing, and found a reservation monitor quietly running 200 API requests an hour around the clock. He called the ban fair 🏷️ Make it prefix every message with an ALL-CAPS project tag (@EliLanger). Everything lives in one iMessage thread, and that is currently the only way to search it 🧨 The honest part: two of the nine payloads are the exact wording the person posted. I wrote the other seven from what they described, in the shape of the two that provably worked. And Reddit produced nothing usable in 8 runs, because everyone who can actually run these is posting on X

Introducing 𝕏 Chat Agents powered by our new 𝕏 Chat API & Chat XDK.
@XDevelopers
One solution is to train the AI to write like you. Specifically: 1. Ask your agent to assemble everything you've ever written. Docs + Slack + X + Other. 2. Then have it write a markdown profile on you, your style and beliefs. 3. Then when it writes, ask it to pull specific words and phrases from what you've written in the past. HT @rwitoff
@brian_armstrong
Built a little agent automation where I paste a link to a cool website I want to save: → checks for duplicates in my notion db → extracts metadata (favicon, x handle, title) → ai classifies as personal site or company/product → pings a small endpoint to capture light and dark mode screenshots → adds the site + all details to my notion db → purges the cache on my /sites page → replies with a tweet draft (in case I want to share) It's probably slightly inefficient compared to making this fully deterministic, but I like having an agent take care of it because I can say things like: - oh, that site you captured has a weird loading state, recapture after waiting 3 seconds - review all sites I've saved in the notion db and see if we accidentally captured loading states/403 errors and re-process Yesterday I tried to save a link that 403d so I had my agent wire up a rotating residential proxy to get around it. Look ma no hands! →

@soarflights
I've been keeping a daily journal for the past ~10 years. Last year I moved everything into Notion. This year I've been steadily adding enrichment automations to fill in a daily recap with meetings from that day, people I met with, highlights from work, and things I read (syncing data from all my main apps). Everything connects nicely with other stuff in my Notion workspace, too. For example, if the automation sees I met with someone new that day, it adds them to my People database + kicks off an enrichment process to pull an avatar, website, x/linkedin/github profiles, etc. — like a little self-populating contacts list. Together, this adds a lot of texture to every journal entry + adds cues for me to journal about by hand. Anyways: connected tools + automations + a great writing surface are pretty great, highly recommend.

Tomorrow was invented in the Last30Days. That's the idea behind the @slashlast30days podcast, launching today. Episode 1 is with @BillyM2k, the founder of Dogecoin. "I quit because I was making more money being an idiot online." He pulled up his X analytics live on the show: → The $177,000 X has paid him for posting memes "I don't know why I'm getting paid to post on X. It's not hard and it's stupid. This is just bonus money for posting stupid shit." → The time @elonmusk offered him a job "He did eventually ask if I wanted to work at X. I was like, probably not at the moment." → How he actually got into X HQ to meet him "I was wandering around asking, I have an appointment with Elon Musk. And they were like, he is not here. I'm like, okay, but he texted me." 📌 Watch now:

Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor. Serving the X community has been the privilege of a lifetime. X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather. The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year. And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more. We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever. None of this would have been possible without the incredible team here. The next leaders will take X to even greater heights with @benjitaylor on design, @singhai on core product engineering and @dinkin_flickaa on mobile engineering -- among many other great people. Thank you to Elon and the X team for welcoming me into the company. See you on the Timeline.
@nikitabier
I’ve come to the realization that X might be the least toxic space for a woman in tech. I was recently featured in a @wsj_com article about solo founders, and it was one of the few bits of media I’ve done that has escaped containment: posts on Facebook, high school friends, random relatives, etc. seem to all have been served the article on social and pinged me nice notes & links. And WOW the public comments on gen pop social posts were a very unwelcome reminder on what it’s like to put yourself out there as a female entrepreneur: being called a fraud, reprimanded to put mothering first, called a liar, presuming “tech exec” is code for “low level product owner”, calling me a no-nothing MBA fake (what?), calling me a Bay Area baby born with a silver spoon (what??!), denigrating my technical chops, comments that my only advantage is being hot, or a TikTok influencer, and getting LinkedIn connections from men asking how I stay looking 25 in my 40s 🫠 Anyway I could not be more grateful for this hellsite where you all take me at face value, I can share honest experiences and thoughts, debate in relative good faith, beep boop my AI hacks, laugh, and only occasionally poke the trolls. I never thought I’d say this: but X is the place I get the most respect online as a leader, engineer, and mom. What a world. If only we could get rid of the AI reply guys and fix search, this might be heaven.

Screen Charm is live on @ProductHunt i made a funny video about my relationship with PH (thanks to my wife for recording it!). on my first PH launch 2.5 years ago, i got only 2 upvotes. because of that terrible experience, i started taking X more seriously. so basically, Product Hunt and especially that failure is the reason i started posting on X. today, i want to say thank you to that experience. i guess i'm a bit more mature now and don't expect anything, but I'd really appreciate your support 👇

alright, what is hitting my site this much in the last 2 days. says it's all coming from the X link shortener, but i couldn't find any tweets linking to https://paulstamatiou.com/
@Stammy
So... "ai, explain what I just did": we ingested 9M+ directed edges from X into a weighted influence graph, then ran a personalized PageRank variant — tuned for human accounts — to surface eigenvector centrality at scale. once you know the high-centrality nodes, you watch their signal propagation before it hits the long tail. beta soon. @digg @basic_in_
