I have a few, my fav is Jessie Gender, who gives insightful reviews but doesnt shy away from criticism of Trek. I also like how she looks at things from a gender critical angle, which is something few peoppe think about. Sean Ferrick is another cool one, as are the guys from Trekyards who are more focussed on tech and ships. Who else should I look up on?
The two that I used to love either have disappeared or significantly slowed down their posting:
Ketwolski - just gone, I hope he’s ok
Trekspertise - use to do a lot of video essays on Trek, I think he got caught up in making a movie (good for him!) so even when they do post it’s just not the same
