John Gruber engagement report
@gruber - 335K followers on X
Measured over 7 original posts from a 30-day window, last computed on October 10, 2026.
Engagement
Early reading. We have captured 7 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 247 interactions against 335K followers, an engagement rate of 0.074%. Posts are seen about 33K times each, and 0.743% of those impressions turn into an interaction. That is about 9.92% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.27 posts a day over the last 30 days, though only 20% of days saw any activity at all. Most posts go out around 23:00 UTC, and Wednesday is the busiest day of the week. Of the 7 posts sampled, 29% carry an image or video, 14% are part of a thread and 57% link out. The account's strongest tracked post pulled 66K interactions, about 266x its own typical post. Only 7 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 23:00 UTC, and Wednesday 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 | 29% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 57% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | -8% | -9% to -7% | 41K |
- 29% 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.
- 57% 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 76 characters, which falls in the under 80 characters band. Across the catalog, posts under 80 characters run 8% below 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.

Join @xAI and help build a purely AI software company called Macrohard. It’s a tongue-in-cheek name, but the project is very real! In principle, given that software companies like Microsoft do not themselves manufacture any physical hardware, it should be possible to simulate them entirely with AI.

The living Israeli hostages held in Gaza have been freed under the first phase of Donald Trump's peace plan, alongside a Palestinian prisoner release. The deal may become a signature achievement of Trump's second term, and it could mark a strategic turning point for the Middle East https://t.co/pQx68wTv8V

Trump on Iranian leaders: "They're gonna make a deal. They did something yesterday that was amazing actually. They gave us a present, and the present arrived today. It was a very big present worth a tremendous amount of money. I'm not gonna tell you what that present is but it was very significant prize."

Before we all mute the word 'dithering' I thought I'd explain a little bit about why we needed to dither digital images in the first place. Although it's an aesthetic now, we used to need dithering to trick our eyes into seeing more colors than were actually there. 👇 https://t.co/HK0zzTnsYr

Some people do crosswords. I fill in redacted names. The redacted email screenshot in Apple’s lawsuit against Michael Ramacciotti and Jon Prosser was set in Arial (of fucking course). So I pixel-fitted the font size and used red text to superimpose the redacted names, along with surrounding words, to show which names fit the redactions exactly:
