Yann LeCun engagement report
@ylecun - 1.3M followers on X
Measured over 6 original posts from a 30-day window, last computed on October 24, 2026.
Engagement
Early reading. We have captured 6 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 340 interactions against 1.3M followers, an engagement rate of 0.025%. Posts are seen about 55K times each, and 0.612% of those impressions turn into an interaction. That is about 4.12% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 15:00 UTC, and Monday is the busiest day of the week. Of the 6 posts sampled, 50% carry an image or video and 50% link out. The account's strongest tracked post pulled 33K interactions, about 97x its own typical post. Only 6 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 15:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 50% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 50% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 50% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 50% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 1358 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

Moderna and @Merck today announced positive topline results from the Phase 3 INTerpath-001 trial evaluating adjuvant treatment with intismeran autogene, a novel investigational mRNA-based individualized neoantigen therapy jointly developed by Merck and Moderna, in combination with KEYTRUDA® (pembrolizumab), Merck's anti-PD-1 therapy, in patients with completely resected Stage IIB-IV melanoma.

1/ I'm a cardiologist. I've practiced for twenty-five years, through a lot of "breakthroughs" that turned out to be press releases. So understand the weight of what I'm about to say: I have never seen a single week in medicine like the one we just lived through. In the span of a few days, four separate scientific breakthroughs landed. The stock market treated them as four unrelated stories and sent a handful of biotech companies soaring. But that's the shallow read. Look closer and they are not four stories at all. They are four faces of the same story — the biggest shift in medicine since the discovery of antibiotics. Medicine is becoming programmable. Individualized. Written for one human being instead of the average of millions. Let me walk you through exactly what happened, in plain language, and show you where this is actually headed. Because the future arrived quietly this week, and most people scrolled right past it.

What's wrong with Trump's $1B White House reno? Four biggies. 1) He lied that taxpayers wouldn't be on the hook for it. 2) Trump asked Congress to fund it. Congress declined; Trump is doing it anyway. 3) Trump is robbing other pots of money, including for the Secret Service and Nat'l Parks, to do it again, in defiance of Congress 4) Trump is soliciting money from unknown donors for unknown amounts, opening the door to corruption and influence peddling. So, yes, this is much worse than a home reno gone wrong! It's a massive separation of powers issue, and Congress ought to make clear NO FUNDING means NO FUNDING. https://t.co/yXpKCvRT5O

Kim Jung Un is the leader of a communist dictatorship. Trump embraces this communist as a friend. Trump also advocates government ownership in private companies. Yet, somehow, Trump supporters want you to believe that “Medicare for all” is the real communist threat. Absurd.

The newer generation cancer vaccines aren't like the HPV shot (that prevents a virus). These are therapeutic, they treat cancer you already have. And 2026 is the year they stopped being sci-fi. The idea: after surgery, sequence your specific tumor, find the mutations unique to it, and build a custom mRNA vaccine that trains your immune system to hunt any cell carrying them. A wanted poster for your personal cancer. Where we actually are: Melanoma: just like in immunotherapy 15 years ago the furthest along. The press release of positive Phase 3 made the headlines yesterday, the first ever for a personalized cancer vaccine. Earlier data: ~49% lower risk of recurrence. Heading to regulators. Pancreatic cancer: arguably the most stunning. In an early trial, patients whose immune systems responded to the vaccine were far more likely to be alive 6 years later, in a cancer where 5-year survival is barely better than 10 %. Now in a larger trial. Kidney, lung, bladder, brain: all in trials, mostly early phase. The honest caveats: these work best after surgery to stop recurrence, not to melt large tumors. They're personalized, so they might cost $100–300k and take weeks to build per patient. And most are still early-phase. First approvals at best 2027. But the direction is unmistakable. The mRNA platform some parts of the internet spent years calling poison - because they got fooled by bad actors making money on their lies - is turning into the most personalized cancer medicine ever made. These are the main trials currently running:

President Trump promised there'd be no cuts to Medicaid. Then he pushed through his One Big Beautiful Bill, which cut Medicaid by nearly $1 trillion and has already caused over 5 million Americans to lose health insurance. Read my take in @nytopinion: https://t.co/aoWJDeQ1Kc https://t.co/DJeO2AkY2F

I’m a scientist. Every time I hit “post,” I hesitate. Not because I doubt the science. But because I know what’s coming. I know someone will call me a shill. Someone will tell me I’ve been bought by industry. Someone will explain my own field to me after watching a 90-second video. Someone will demand a source, then reject the source because they don’t like who funded it. And someone will confidently tell thousands of people that I’m lying. That is the strange reality of communicating science online. You spend years learning how uncertain science can be. Then you enter a world where the most confident person in the comments often knows the least. But I keep hitting “post.” Because if scientists decide that communicating science isn’t worth the abuse, the people with the least hesitation get to explain science instead. And that seems far more dangerous.

In 2024, Trump claimed to have “a concept of a plan” to replace Obamacare and bring down health insurance costs. No plan was ever enacted, but he still sabotaged Obamacare. Now millions of Americans are paying thousands more on premiums every year. My final @nytopinion Chart: https://t.co/MbaCP4s5Ez

- What is Yann LeCun's engagement rate on X?
- Yann LeCun (@ylecun) has an engagement rate of 0.025%, based on the median interactions across 6 original posts from the last 30 days against 1,346,358 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.025%, Yann LeCun sits above the 25th percentile of the 204,583 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
