That's a great point, and is in fact something I wanted to touch upon in my previous comment. Being able to choose great subreddits is a big plus, and to be fair there are great YT creators who create great niche content. But a common theme has been that they usually start small in size (hence niche) but the moment they grow big, they start to "look" similar to the large channels/subreddits: for YT, they start getting bombarded with clickbait titles, sponsored videos (not just an ad/video). For reddit, "funny"/"flaming" comments hijack every discussion.
