I find plenty of interesting videos, but I needed to slowly craft my following list.

I started with some CS lectures, and conference talks and it was alright, but something I reached for out of necessity.

Once I started watching videos out of curiosity I slowly ended up finding channels around my hobbies that filled my feed with pretty interesting stuff. There's good content out there beyond dense lectures, but also a lot of crap. I built my curated list of channels making videos worth watching and rarely watch something outside of those.

Similarly to music discovery, once you find what you like keep an eye on neighboring artists. I stay curious, but I'm quick to reject.
