Doesn’t really matter since people upvote it anyway. Complaining about reposts and stuff is as much spitting into the wind on lemmy as it was on reddit. People hate that their one downvote can’t bring down a post, so they comment instead, get a few upvotes there, feel better, and then return to the same site they constantly complain about anyway.
I use Youtube more than any other service. If you like video essays, documentaries, and other medium- and long-form content, it’s the only place on earth to get it. Cable television ditched intelligent content long ago. Nebula and Curiousity are okay, but most of the content that I couldn’t already get on Youtube has that shitty cable tv vibe.
The only downside with Youtube is it’s huge and the algorithm is iffy. It can take a long time to build up a library of subscriptions that provide high level content every day. But now that I have that, it’s basically my exclusive streaming platform. I watch 1hr of Netflix/HBO/whatever with my wife every night, and all the rest is history, cooking, science, etc. on Youtube.
