Brian Greene engagement report
@bgreene - 1.2M followers on X
Measured over 1 original post from a 30-day window, last computed on October 25, 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 1.3K interactions against 1.2M followers, an engagement rate of 0.111%. Posts are seen about 48K times each, and 2.78% of those impressions turn into an interaction. That is about 3.99% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.03 posts a day over the last 30 days, though only 3% of days saw any activity at all. Most posts go out around 19:00 UTC, and Friday is the busiest day of the week. Of the 1 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 8.9K interactions, about 6.7x 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 19:00 UTC, and Friday 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 | - | -8% | -9% to -7% | 41K |
- 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 70 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.

Is math discovered or invented? Most scientists say discovered. I used to agree. But I’ve come to think we invent systems to impose order, and math is our most powerful language for expressing that order. https://t.co/lZIdqHP1JT

A simple quantum truth that never ceases to delight: We spend our lives floating on a sea of repelling electrons. We never truly touch anything. What we call "touch" is just the sensation of our electrons pushing against the electrons in everything around us. https://t.co/ZvMVbZqSba

What people often get wrong: In quantum teleportation, it's not matter that's teleported. Instead, quantum information describing matter is teleported. Which raises the deep question: Are you the sum of your information? I think so, but would surely hesitate to find out. https://t.co/ehbjejpCzd

What is consciousness? Many see this as the deepest mystery. My guess: One day, when digital systems claim to have inner experiences, we will just shrug and accept that consciousness accompanies sufficiently rich and robust information processing. https://t.co/DAWgWOZHoQ

Can we visualize higher dimensions? After 40+ years working on the math, the best I can do is imagine lower-dimensional analogs and projections, like this hypercube. Some claim to truly see higher dimensions. I’m not one of them. https://t.co/FBQGoJOjof
