I’ll be curious to see the “tutorial videos” — recipes/cooking, music teachers, tech how-to’s, those sort of posts — and how they operate with the ability to zap.
My guess is it will prioritize quality over engagement/clickbait
But also, with the short “life span” of any post currently, I’d imagine there will also be demand (from content creators, at least) for some algorithmic options, to get their presumably-valuable content in front of more eyes.
