I don't really understand the point of shorts (aside from trying to compete with TikTok). It's an arbitrary limitation of video runtime and locked to a phone screen resolution. So dumb.
And how many Youtube-based creators have adapted them SO FUCKING POORLY. The worst I've seen is the Modern Rogue, who have chopped their existing library into like ten thousand shorts. It made being a subscriber to their channel fucking useless because you'd get small snippets of content you'd already seen just shuffled up and out of context. It was especially bad before Youtube separated them into their own tab.
Many others just use it as a "dump this tiktok to Youtube as well" place.
