Engagement
A typical post picks up 1.1K interactions against 439K followers, an engagement rate of 0.247%. Measured over 41 original posts, its engagement rate beats 84% of 20,444 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 64K times each, and 1.70% of those impressions turn into an interaction. That is about 14.5% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 41 original posts from a 30-day window, last computed on September 24, 2026. Recurring tags: #astronaut, #tribfest26.
