Justin Kan engagement report
@justinkan - 627K followers on X
Measured over 1 original post from a 30-day window, last computed on October 11, 2026.
Engagement
Early reading. We have captured 1 original post 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 63 interactions against 627K followers, an engagement rate of 0.01%. Posts are seen about 109K times each, and 0.058% of those impressions turn into an interaction. That is about 17.4% 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 13% of days saw any activity at all. Most posts go out around 17:00 UTC, and Tuesday is the busiest day of the week. Of the 1 posts sampled, 100% carry an image or video and 100% are part of a thread. The account's strongest tracked post pulled 58K interactions, about 916x its own typical post. Only 1 original post 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 17:00 UTC, and Tuesday 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 | 100% 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 |
- 100% 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 241 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.

Today we announced Vessel, a project focused on rethinking perfusion from the ground up, extending how long life can be sustained, and expanding what’s possible in transplantation and critical care. Life-support technologies like ECMO can keep patients alive when the heart or lungs fail, but they aren’t designed for long-term use. Vessel exists to close the gap between what perfusion technology is fundamentally capable of and how it is deployed in daily practice. Our founder and CEO Max Hodak spoke with @WIRED's @emilylmullin about how neural interfaces and Vessel are both longevity technologies, and that is the goal of Science. https://t.co/QtxXQGZl8T
