Uncle Bob Martin engagement report
@unclebobmartin - 286K followers on X
Measured over 58 original posts from a 30-day window, last computed on September 23, 2026.
Engagement
A typical post picks up 289 interactions against 286K followers, an engagement rate of 0.102%. Measured over 58 original posts, its engagement rate beats 60% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 29K times each, and 1.00% of those impressions turn into an interaction. That is about 10.1% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.8 posts a day over the last 30 days, with activity on roughly 67% of days. Most posts go out around 12:00 UTC, and Thursday is the busiest day of the week. Of the 58 posts sampled, 17% carry an image or video and 17% link out. The account's strongest tracked post pulled 2.7K interactions, about 9.4x its own typical post.

Compared with accounts its own size
Uncle Bob Martin's engagement rate beats 60% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 43% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.102%, Uncle Bob Martin sits above the 25th percentile of the 204,956 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 12:00 UTC, and Thursday 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 | 17% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 17% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 17% 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.
- 17% 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 231 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.

For the past several months I've been working on this hypothesis that agents need to be constrained by a harness of deterministic tools that force them to follow a strict process. Gherkin, Code, Unit Tests, Crap, Mutation Tests, etc. But while I've been hammering away on that, the models have gotten astronomically better. I'm starting to think that I'm over constraining them. Perhaps vastly over constraining them.

Have you noticed that when you call businesses an AI sometimes answers? I called a plumber recently and “Rudy“ answered. Rudy was so friendly and effusive that I immediately suspected that it was an AI. So I asked it, point blank, are you an AI? Rudy answered “yes I’m your helpful AI assistant”. Then it and I had an extremely efficient, very pleasant, conversation about what I needed. It knew all the facts, had the schedule right there, I got an appointment confirmed within 90 seconds. I was not put on hold, I was not subjected to someone who could not speak the language, I was not subjected to someone who is so new to their job that they didn’t know how to find the keys on the keyboard. It was a remarkably good experience. Soon, everything is going to be like that. No more “Press one for…”.

Given that agents still need high level supervision. And given that the human review of code is a bottleneck. And given that the models have gotten good enough that strict deterministic harnesses are suboptimal. Then how should we supervise their output. My current solution is to use an interrogation tool coupled with an agent. The tool displays the structure of the system in a UML-like diagram, color coded with crap and mutation scores. The diagram is dynamic, allowing the user to click on element and drill down through the architecture -- all the way to code. The user can detect structures that need improvement and tell the associated agent to make the appropriate changes. These changes can range from high level architectural changes, to the lowest level code refactorings. The associated agent will make those changes and cause them to be redisplayed. The tool I'm using is custom made for me, but you can point an agent at it and use it as a template to build your own custom tool. It's a work in progress, so don't be surprised if it changes a lot over the next few weeks. But then you probably won't care because by then you'll be deep in customizing it for yourself. And anyway, you can always point an agent back at mine, or someone else's, and integrate improvements into your own. https://t.co/tu0Dsc9Vta.

It is very spooky how good @grok is getting. I'm having in-depth design discussions with it, and it is contradicting my incorrect assumptions, finding gaps in my reasoning, and showing an immense amount of insight into the issues. It's not hyper-creative, but there are hints of creativity. Spooky.

I am getting monstrous amounts of work done simply by issuing a well considered prompt every ten minutes or so, and by not being afraid to try things that I used to consider expensive. The time between those prompts is spent watching investment podcasts. It is eerie just how good @grok is now. I've stopped using any other model for the time being. That'll likely change.

General rule of thumb for success. Don't be afraid to try things! Especially things that everyone else dismisses. You know, like electric cars, reusable rockets, solar power, self-driving cars, UML.

- What is Uncle Bob Martin's engagement rate on X?
- Uncle Bob Martin (@unclebobmartin) has an engagement rate of 0.102%, based on the median interactions across 58 original posts from the last 30 days against 286,032 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.102%, Uncle Bob Martin sits above the 25th percentile of the 204,956 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.
- Does @unclebobmartin have real engagement?
- Its engagement rate beats 60% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @unclebobmartin post?
- Most posts go out around 12:00 UTC, and Thursday is its busiest day, at roughly 2.8 posts per day across the measured window.
