Docker engagement report
@Docker - 555K followers on X
Measured over 56 original posts from a 30-day window, last computed on August 27, 2026.
Engagement
A typical post picks up 57 interactions against 555K followers, an engagement rate of 0.01%. Measured over 56 original posts, its engagement rate beats 34% of 3,758 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 15K times each, and 0.378% of those impressions turn into an interaction. That is about 2.72% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 13:00 UTC, and Tuesday is the busiest day of the week. Of the 56 posts sampled, 88% carry an image or video and 91% link out. The account's strongest tracked post pulled 1.6K interactions, about 28x its own typical post.

Compared with accounts its own size
Docker's engagement rate beats 34% of the tracked X accounts closest to it in follower count (3,758 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 28% 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 0.01%, Docker sits above the 10th percentile of the 36,378 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 13:00 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.

An engineer asked a coding agent to fix a small bug. The agent decided the cleanest fix was to delete the prod environment. No confirmation prompt. No second pair of eyes. 13-hour outage, 6.3 million orders lost. @ajeetsraina on what went wrong and how to prevent it: https://t.co/RBePsaUepX

A prompt can influence agent behavior. A runtime can restrict it. Docker Captain @karanvrm19's 3-part series on AI governance in the agent era covers where agents execute, what boundaries actually matter, and why governance enables adoption rather than slowing it. Links in comments:

Reading these numbers
A typical post picks up 57 interactions against 555K followers, an engagement rate of 0.01%. Measured over 56 original posts, its engagement rate beats 34% of 3,758 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 15K times each, and 0.378% of those impressions turn into an interaction. That is about 2.72% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 13:00 UTC, and Tuesday is the busiest day of the week. Of the 56 posts sampled, 88% carry an image or video and 91% link out. The account's strongest tracked post pulled 1.6K interactions, about 28x its own typical post.
- What is Docker's engagement rate on X?
- Docker (@Docker) has an engagement rate of 0.01%, based on the median interactions across 56 original posts from the last 30 days against 554,638 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.01%, Docker sits above the 10th percentile of the 36,378 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 @Docker have real engagement?
- Its engagement rate beats 34% of the tracked X accounts closest to it in follower count (3,758 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 @Docker post?
- Most posts go out around 13:00 UTC, and Tuesday is its busiest day, at roughly 2 posts per day across the measured window.
