In terms of English go content I would add Michael Redmond, Yoonyoung Kim, Young Sun Yoon (Yoon’s Baduk Cafe), Stefanie Yin and Ryan Li (NYIG).
For amateur player go content in English also worth mentioning would be Youngwoon Park (Baduk Doctor), Nick Sibicky, Dwyrin etc.
There’s probably more but off the top of my head
