I haven't commented on this thread yet? Oh well, probably for the best. I remember commenting on a thread like this on Oro Jackson, while I was still just following the algorithm's recommendations and getting oddly into a variety of channels, most of which I just don't care to watch anymore, and honestly my tastes in YouTube channels tends to change and evolve over time. Some channels I get really into for a couple months, and then stop watching afterwards. And in some cases, it might be because the novelty of the new channel has passed, it might be because the type of content is something I don't want to watch anymore, it might be because I finally realised the channel content isn't for me.
Still, I generally tend to like watching: Doobus Goobus, Kurzgesagt, Casually Explained, Terrible Writing Advice, and friendlyjordies.
