Listening to music and watching dance lessons on YouTube makes me happy. Everything else on YouTube makes me unhappy. It doesn't matter what the video is, watching YouTube makes me unhappy.
If all of YouTube made me unhappy then I should just not use YouTube. But I like listening to music and watching dance lessons on YouTube. I dislike getting recommendations for non-music non-dance videos. Fortunately, YouTube personalizes its recommendations. I wondered if I could train YouTube to only recommend music and dance lessons.
I created a brand new Google account just for YouTube. I carefully refrained from clicking on anything other than music and dance lessons. I quickly learned that "Don't recommend channel" works better than "Not interested". If you press "Don't recommend channel" then YouTube will stop recommending the channel.
I have trained my YouTube algorithm for about two years now. When I wanted to watch a non-music non-dancing video I did it incognito or on another account. Here are what my homepage recommendations look like right now.
The first 12 recommendations are all music. The 13th recommendation is a clip related to Doctor Who. I think the non-music Doctor Who recommendation came from clicking on The 10th Doctor Epic Suite which got recommended because I was watching music from Sherlock. From there, the next 72 recommendations are all music.
If I just keep scrolling and scrolling until I get non-music non-dance recommendations, they tend to be silly stuff like this, this or this. I think the Lord of the Rings recommendations come from listening to fantasy-themed music.
If you want to use YouTube for a specific purpose without distractions then it is entirely possible to train YouTube to do this. All you have to do is create an account, watch videos on a specific topic and press "Don't recommend channel" whenever you encounter an off-topic recommendation.
I found, when I tried to do this over a year ago, that no matter how much effort I put into "pruning" the home screen, YouTube would always devote ~10-20% of it to stuff I didn't want to see. Either it was epsilon-exploration, or stuff that tested well with the general population, or a bunch of "mandatory modules" like popular music or "news," but whatever it was, I couldn't get rid of all of it, and some of it managed to attract my clicks despite my best efforts. These extra items filled me with a sense of violation whenever I scrolled through.
So, I wound up using a CSS editor to block the main content of the youtube index page, as well as that column of recommended videos that gets shown next to the player. Here's my custom stylesheet:
Now when I visit youtube.com, I get a blank page, and have to click on "subscriptions" in the left column to get the user experience I want, plus I get recommended videos only when I FINISH a video. This is a far more pleasant experience, and I am able to use YouTube for pretty much only classical music, cooking tutorials, and the occasional education video, without ever getting pulled into things I don't want.
Speaking of the recommendation algo, btw, it's also super awesome. It has somehow consistently surfaced new classical music composers to me, and has played a major role in the development of my tastes and interests over the past few years. Without it, I doubt I would have been exposed to Schnittke or Bruckner, for example. Way better than spotify, and I haven't found anything to replace it, sadly.
Stylebot for chrome. Perhaps there's better now — the ui can be a bit wonky — but I've used it for almost a decade, so
