I noticed Youtube shorts also seems to update the feed based on how long the last video you watched. If you're scrolling quickly then stop to watch a dog video long enough the next one is likely to be another dog video.
Facebook does the same. The longer I dwell on an image post, the more likely the next batch of posts would be similar
I’ve noticed the same thing and this creates such a negative user experience. Every short is a reaction test and if I fail, I get slop. Makes the whole experience very jarring (for better or for worse).
I've been insta-skipping tennis video's for months now. Still getting Federer on a daily basis.
One of my gripes with youtube at the moment is that they break my adblock filters to remove shorts more often than they break the filters stopping the actual ads.
