Isaac Arthur (
https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g)
He's a YouTuber who makes pop-sci videos on futuristic concepts like fusion energy and space habitats. His videos are really good in that they go into far greater depth than any other pop-science channel on YouTube whilst simultaneously being comprehensible to scientifically illiterate retards such as myself. His videos are so good that other pop-science YouTubers like Because Science feel inadequate and shallow by comparison, because they are.
However, he's an autistic sci-fi geek with a speech impediment- the exact kind of person you'd expect to be a lolcow. He sets multiple rules for himself to avoid cowdom.
First of all, he almost always avoids talking about politics. Despite this, the subject does occasionally come up, as his videos often involve discussion of the social ramifications of one technology or another. When politics do come up, Isaac always does his best to pay his respects to both sides of the issue in a way that is moderate and realistic. This is doubly impressive because Isaac Arthur's day job is actually political- he works as a member of the Board of Elections for the state of Ohio. You can see his linkedin page here. (

Secondly, he avoids talking about himself in the vast majority of his videos, despite his personal life being intensely interesting (he got a degree in physics at a young age, only to join the army and become an artilleryman). He talks about the subject here: (

He consistently gives shoutouts to YouTubers with fewer subscribers than he does and is careful to give credit to the actual physicists who came up with the ideas that he often discusses in his videos.
Thirdly, he has put in serious effort towards correcting his speech impediment, to the point at which his current videos sound distinctly better than his older ones. Despite this, he's consistently self-deprecating about his impediment and always includes subtitles for his videos so that everyone can understand what he's saying.
Finally, the dude consistently involves himself in his own community, holding monthly Q&A livestreams and regularly polling his fans for what subjects they want to hear discussed.
