It's FOSS engagement report
@Itsfoss - 172K followers on X
Measured over 33 original posts from a 30-day window, last computed on September 20, 2026.
Engagement
A typical post picks up 70 interactions against 172K followers, an engagement rate of 0.041%. Measured over 33 original posts, its engagement rate beats 41% of 15,519 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 5.5K times each, and 1.28% of those impressions turn into an interaction. That is about 3.18% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.7 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 14:00 UTC, and Thursday is the busiest day of the week. Of the 33 posts sampled, 33% carry an image or video and 64% link out. The account's strongest tracked post pulled 829 interactions, about 12x its own typical post.

Compared with accounts its own size
It's FOSS's engagement rate beats 41% of the tracked X accounts closest to it in follower count (15,519 accounts, accounts of similar size (decile 8 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 50% 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 0.041%, It's FOSS sits above the 25th percentile of the 156,839 accounts in this comparison. That places it in the below the median band, which runs 0.022% to 0.128%.

Posting timing
This account posts most often around 14:00 UTC, and Thursday 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 | 33% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 64% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 33% 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.
- 64% 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 219 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.

Swift 6.4 introduces Swift Build as the default SPM engine, giving Linux developers the exact same build workflow as Xcode on macOS. This means automatic dependency management, CPU-optimized binary compilation, and built-in SBOM generation. The VS Code extension is now on Open VSX, not just Microsoft's marketplace. So that's another W for open source developers.

Firefox 156 brings performance boost to its built-in PDF viewer. If you view PDF files in Firefox browser, you will notice the improvements. That's not it. Firefox now also uses less CPU and memory when displaying large JPEG images that are scaled down on a webpage. The update also includes fixes for FLAC audio playback, platform-specific issues, and other bugs. Altogether, small improvements that should make browsing with Mozilla Firefox even better πΊ

AI policy enforcement in open source projects could lead to a messed up situation. And the Void Linux episode is an example. A maintainer orphaned 113 packages. Here's what happened. A contributor submitted a Go package update. He had used AI to generate comparative text between versions. Problem was that he didn't disclose the AI usage upfront in the PR as Void Linux's policy requires. When challenged, he disclosed it and then orphaned 113 packages in protest, including Alacritty, Kubernetes, Docker tools, and fscrypt. Unless others step in, and someone will, those packages lose active maintenance. Policy clash or ego clash? Either way, not a good outlook for open source community.

- What is It's FOSS's engagement rate on X?
- It's FOSS (@Itsfoss) has an engagement rate of 0.041%, based on the median interactions across 33 original posts from the last 30 days against 171,665 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.041%, It's FOSS sits above the 25th percentile of the 156,839 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 @Itsfoss have real engagement?
- Its engagement rate beats 41% of the tracked X accounts closest to it in follower count (15,519 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 @Itsfoss post?
- Most posts go out around 14:00 UTC, and Thursday is its busiest day, at roughly 1.67 posts per day across the measured window.
