alt Hacker NewsShort form video inherently has fundamental differences to what it will support and optimize towards. Just the selection effect of who prefers to watch shorts over long form content produces a different optimum that IMO is far worse.
Take a population, and then remove anyone who is willing to invest more than 60 seconds on a idea, and then sample the "preferences" of that population.
What did you expect to end up with?
Creators who I really like still end up producing trash on shorts because that's what gets traction, because the problem is what is actually liked by someone who wants to just mindlessly scroll 30 seconds at a time is really bad
No, there was an extremely quick and obvious drop-off in quality that is not excused by "vertical short video has different dynamics"
Before the change my shorts feed roughly aligned with my main homepage feed (which has also gotten worse since they made the dislike button a placebo there). After, it's mostly AI voiceovers reading out Reddit or Twitter comments about life situations, placed over Minecraft gameplay. This is probably a convergent point in the algorithm as you said but it's also extremely relevant that I have no way to tell it "stop that"
