I just subscribed to Nebula. Lots of great video essayists on there from YouTube (e.g., LegalEagle, Not Just Bikes, MuneCat, Philosphy Tube, Lindsay Ellis, F.D. Signifier, CityNerd, &etc.), extended and unreleased content as compared with their YouTube channels. Also no ads, because you're paying the creators for the quality content. (I got 40% off through this link: go.nebula.tv)
