I'm hesitant to answer with specific recommendations because I think there is a lot of truth-stretching and self-promotion in this space. Nearly all of them are trying to make a buck, which I don't think is inherently wrong (people have to earn a living, and they do have unique skills/experiences/viewpoints to offer) but certainly clouds the issue further.
The majority of them also have views that I find pretty problematic.
What specific channels would you recommend?
