I did, before I disabled the watch history which then also disables shorts, effectively. Shorts may be the wish/temu version of TikTok (though increasingly less so), but is absolutely as addictive.
I don't think it matters if it's better or worse. There are plenty of bad browser based email implementations. I think we should be encouraging companies to borrow and steal good software ideas from each other, because otherwise we end up stifling innovation.
I don't know why exactly, but I don't get almost any "watch part 2" content on YouTube shorts. That's actually the only reason I started using it instead of TikTok - those really enraged me.
