Captain Disillusion
Extremely talented VFX artist deconstructs internet video hoaxes. Has pivoted recently into explaining VFX and video basics. High production, entertaining and informative.
ContraPoints
Video essayist that brings a very thoughtful and well researched view into the dregs of internet culture, social justice, and modern issues.
Mark Rober
NASA Engineer does silly experiments with a decent budget and technical knowhow. Like if Grant from Mythbusters had his own show and didn't pad out each 1 hour program with 45 minutes of filler.
hbomberguy
A games reviewer/LPer turned video essayist that sometimes still does games. Hilarious, good logic, likes to take down easy targets (Paul Joseph Watson, Steven Crowder, et al).
Retsupurae
Quite possibly the first LP group, often play throuhg intensely hilarious and terrible games. Sometimes stop to mock awful YouTube videos MST3K-style.
TheOdd1sOut
A 22-year old aspiring math teacher creates animated videos about his life and thoughts. Geared towards a younger demo, but I find him charming and funny.
