Current activity is observable; historical growth is not
The estimate uses public post timestamps and visible engagement, not invented trend lines. It shows current momentum separately from subscriber count and does not forecast future members.
How the activity score works
The tracker reads current community metadata and up to 25 recent non-pinned posts, then applies a fixed, reproducible formula weighted 60/25/15 across posting pace, comment depth and sample completeness.
Use momentum to prioritize research
A current activity estimate helps you decide which communities deserve deeper reading today. Pair it with subreddit stats and the best time to post before you submit.
