Udi Wertheimer engagement report
@udiWertheimer - 229K followers on X
Measured over 48 original posts from a 30-day window, last computed on October 1, 2026.
Engagement
A typical post picks up 178 interactions against 229K followers, an engagement rate of 0.078%. Measured over 48 original posts, its engagement rate beats 54% 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 18K times each, and 1.02% of those impressions turn into an interaction. That is about 7.64% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 4.1 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 04:00 UTC, and Monday is the busiest day of the week. Of the 48 posts sampled, 27% carry an image or video and 21% are part of a thread. The account's strongest tracked post pulled 16K interactions, about 89x its own typical post.

Compared with accounts its own size
Udi Wertheimer's engagement rate beats 54% 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.

At 0.078%, Udi Wertheimer 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 04:00 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 | 27% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 4% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 27% 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.
- 4% 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 253 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.

As a kid, I always wished Pokémon battles in the games could play out like they do in the anime. So I built a real-time Pokémon battle experience with @fal H3 Max. choose a move, the game calculates the outcome, and AI generates the animation on the fly. Paralysis, fainting, and Pokémon is hurt are reflected on screen. Project:https://t.co/wlsMg3tQEV

I used GPT-6 Astra to get AAA PC games running on my iPad mini! Skyrim, Batman: Arkham City, Hades, and Age of Empires II. The actual Windows versions, running locally with touch controls. No streaming. Demo below and I'll share a repo and setup guides soon! https://t.co/zz8ze2R6Qn

now starts a short period of time when creative people who are extremely good at prompting are so much more productive at making games, shorts, movies, and other content, that they can compete starting from zero and make new empires. maybe a year until people catch up

Good programmers state they use models like GPT 6 Astra without obtaining good results: it makes me feel I live in a parallel universe. But the explanation is not that hard: good programming in the past and now requires a different skill set, even if there is some overlap.

- What is Udi Wertheimer's engagement rate on X?
- Udi Wertheimer (@udiWertheimer) has an engagement rate of 0.078%, based on the median interactions across 48 original posts from the last 30 days against 229,091 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.078%, Udi Wertheimer 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 @udiWertheimer have real engagement?
- Its engagement rate beats 54% 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 @udiWertheimer post?
- Most posts go out around 04:00 UTC, and Monday is its busiest day, at roughly 4.13 posts per day across the measured window.
