There are only a handful of important channels I follow on YouTube now. Plus a lot of distractions, making it easier to break my addiction to YouTube to work on /s/LeverMind (coming soon - let me know if you want to help with that or /s/Projex). Regretfully I have chosen to NOT embrace alternative media in order to break my video addiction, with meager results.

IMO, the only "important" worthy channels I still try to follow (off the top of my head without actually delving into my subscribed list):

Academy of Ideas - https://www.youtube.com/c/academyofideas/videos
Alison Morrow - https://www.youtube.com/c/AlisonMorrow/videos
DRUTHERS - https://www.youtube.com/c/DRUTHERS/videos
Eric Hunley - https://www.youtube.com/c/erichunley/videos
Geopolitics & Empire - https://www.youtube.com/c/GeopoliticsEmpire/videos
Ice Age Farmer - https://www.youtube.com/c/IceAgeFarmer/videos
reallygraceful - https://www.youtube.com/c/reallygraceful/videos
The Jimmy Dore Show - https://www.youtube.com/c/thejimmydoreshow/videos
Viva Frei - https://www.youtube.com/c/VivaFrei/videos
Zoon Politikon - https://www.youtube.com/c/ZoonPolitikonHollySeeliger/videos

This is a very sad short list. I hadn't realized it had gotten so short.

If you can think of any I've forgotten (likely many) or need to discover, let us all know.
