Stack Overflow engagement report
@StackOverflow - 256K followers on X
Measured over 19 original posts from a 30-day window, last computed on September 9, 2026.
Engagement
A typical post picks up 8 interactions against 256K followers, an engagement rate of 0.003%. Measured over 19 original posts, its engagement rate beats 13% of 6,874 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 5.5K times each, and 0.145% of those impressions turn into an interaction. That is about 2.16% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.63 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 10:00 UTC, and Tuesday is the busiest day of the week. Of the 19 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 77 interactions, about 9.6x its own typical post.

Compared with accounts its own size
Stack Overflow's engagement rate beats 13% of the tracked X accounts closest to it in follower count (6,874 accounts, accounts of similar size (decile 7 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 10% 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 0.003%, Stack Overflow sits above the 10th percentile of the 66,128 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.016%.

Posting timing
This account posts most often around 10:00 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 | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 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.
- 100% 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 398 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above 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.

You've spent years building valuable technical knowledge—but it's scattered across PR comments, documents, and code environments. Then your team and AI agents use unverified and stale context, making mistakes at scale. Enter the new Stack Internal platform experience. We're turning scattered context into a living enterprise memory - and it's only the beginning. Learn about the new capabilities of Stack Internal and how we're building the future of trusted knowledge for people, teams, and agents: https://t.co/NsIcp3sMFV

Prompts sent, tokens spent, and lines of code generated can seem like good metrics when tracking your AI productivity. But they fail to answer one important question: did your software get any better? Our VP of Product Alex Lato shares with @hackernoon the real cost of only measuring AI productivity, and why engineering leaders should be focusing on outcomes and developer satisfaction instead. https://t.co/lqsAVIucrJ

AI allows engineering teams to generate more code than they can reasonably review. This creates a real problem that goes beyond just code quality, our Chief Product and Technology Officer Jody Bailey shares with CTO Uncovered, especially when important technical judgement lives solely in the heads of your engineers. The good news? Your technical teams already have the solution, now you just need to document it. https://t.co/6OVGBoUQSa

If your favorite kitchen knife kept changing shape, you’d probably stop using it. The same goes for our dev tools, which we love because of their predictability and trustworthiness. But what happens when agentic coding fundamentally changes the nature and stability of these tools? Ryan Donovan dives into how our dev tools build trustworthy processes, the ways that tool changes highlight but can’t fix broken processes, and where tooling and culture can work together to build new trust. https://t.co/TXH2st7PW9

Reading these numbers
A typical post picks up 8 interactions against 256K followers, an engagement rate of 0.003%. Measured over 19 original posts, its engagement rate beats 13% of 6,874 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 5.5K times each, and 0.145% of those impressions turn into an interaction. That is about 2.16% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.63 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 10:00 UTC, and Tuesday is the busiest day of the week. Of the 19 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 77 interactions, about 9.6x its own typical post.
- What is Stack Overflow's engagement rate on X?
- Stack Overflow (@StackOverflow) has an engagement rate of 0.003%, based on the median interactions across 19 original posts from the last 30 days against 256,450 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.003%, Stack Overflow sits above the 10th percentile of the 66,128 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 @StackOverflow have real engagement?
- Its engagement rate beats 13% of the tracked X accounts closest to it in follower count (6,874 accounts), which puts it in the bottom quarter for its size 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 @StackOverflow post?
- Most posts go out around 10:00 UTC, and Tuesday is its busiest day, at roughly 0.63 posts per day across the measured window.
