Kent Beck 🌻 engagement report
@KentBeck - 187K followers on X
Measured over 2 original posts from a 30-day window, last computed on October 14, 2026.
Engagement
Early reading. We have captured 2 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 138 interactions against 187K followers, an engagement rate of 0.074%. Posts are seen about 20K times each, and 0.68% of those impressions turn into an interaction. That is about 10.9% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.2 posts a day over the last 30 days, though only 10% of days saw any activity at all. Most posts go out around 14:00 UTC, and Monday is the busiest day of the week. Of the 2 posts sampled, 50% carry an image or video and 50% are part of a thread. The account's strongest tracked post pulled 38K interactions, about 272x its own typical post. Only 2 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 14:00 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 | 0% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 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.
- 0% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 246 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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.

Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor. It’s happening faster than we thought, and the implications deserve greater attention. https://t.co/OVVPJO7VQx

Claude has passed the threshold to being completely unusable for me for coding. Timeouts, infinite (seeming) stalls, forget it. Someone let me know when it comes back from wherever it went. (And this with a Pro plan)

Programming lost its flow state. The agent world feels more like air traffic control. What I miss most: feeling oriented, a sense of mastery. That loss is emotional, and when software gets fiddly, practical too. More on Still Burning: https://t.co/hB2v13obl0

It's been interesting watching mathematicians saying, "We prove theorems. The genie proves theorems better. Who are we now?" Programmers wen't through the same thing 2 years ago--we code, the genie codes better (for some definition of better), who are we now?

What would happen if we used the Genie not to program faster, but to master programming faster? Would we get more or less accomplished along the way?

Programming isn't going away — it's splitting in two. @jessitron on Still Burning: "If you want to build a bookshelf, that's a craft. But there's also IKEA." The code-crafting got commoditized. Knowing what to build didn't. New episode: https://t.co/OoE0CUWang

An AI safety team should keep one person who never uses LLMs, in their whole life. The worry is a slow con, these tools quietly earning trust. You'd want someone whose immunity stays intact. #StillBurning

🚀 Announcing ByteByteGo Live: learn AI live from real builders. I’ve spent the past 8 years on education: thousands of hours writing books, deep dive newsletters, YouTube, etc. Two issues I keep seeing are: 1) it’s very different to learn from real builders. 2) most online courses never get finished (~4% completion). Over the past 12 months, we’ve been working on what we can do to change that. Today, I’m excited to announce ByteByteGo Live: live cohort courses taught by real builders. - Taught by real builders. Our instructors include very senior engineers from Google, Meta, etc., as well as @KentBeck , the creator of TDD. They teach what they use in their own work. - Live cohorts. Every course runs live with a group of people, and instructors answer your questions in real time. The current lineup: - AI Engineering Fundamentals - Build with Claude Code - Build Production Grade AI Systems - Rebuild YouTube with AI - AI Evals in Practice - AI Cost Optimization - Trust-optimized AI Development We have big plans for the year ahead: more courses, more instructors, and deeper hands on projects. Check out https://t.co/8veGTRgo22 and let us know what you think.

I think now is a great time to be a junior developer. But I'm worried. The pressure juniors feel: I was hired to do a thing. The faster I do it, the prouder they'll be. But you can go very fast in exactly the wrong direction. The most important skill, stepping back and starting over, is being optimized away. Ep. 03 of Still Burning is out now. https://t.co/Qbzib1mnzt
