If you want to build on youtube, my advice, which I don't listen to myself lol, is its all about audience retention today - you need to have something that someone watches through - but you also need audience interaction - so people have to link, share, etc. ,your videos - so you do like high quality videos, that are deep dives - and you do enough of them, like once a month, you probably will gain traction - like into topics related to topics - I could do this also, but honestly I can't be bothered anymore. I have not seen any channel, that did not do high quality content, put out something regularly - that is non politic related - not grow. - Hope that helps + I read your review of the backrooms and I do concur!
