Is interest growing?

Comments are sampled top-sorted per video, our own cap, not the video’s total. A day’s count is therefore driven by which videos were published recently and how much of their top conversation we pulled, not by how much was said that day, which is why the early weeks of the window sit near zero. This is a single collection run; a second run is what turns this chart into a genuine week-over-week read.

Momentum is a percentile rank among the 262 subjects in this run, not a rate: a score of 99 means almost every other subject is moving slower, not that interest doubled. Both lifts are smoothed, so a subject with nothing in the prior window reads as a large multiple rather than an infinite one, and a subject that appears only in the recent window can rank high on a handful of videos. The uploads and mentions columns are there so the multiple can be read against the count behind it.

Late share is read from the comments we sampled, top-sorted, so it says which subjects’ most-liked conversation kept arriving, not how many people watched late. A share near the top of this list on a subject with few comments is a hint, not a finding; the count beside each row is there to be weighed.
