Biblaridion - "Alien Biospheres" is a great popsci series about speculative evolution. He also does constructed language stuff, but I haven't gotten around to diving into that.
Channel 5 with Andrew Callaghan, formerly All Gas No Brakes (had a falling out with behind-the-scenes business types) - a feet-on-the-ground look into various subcultures and events. If you see beyond what's usually a hilarious and definitely slightly voyeuristic facade of "haha people are weird", at its core it's excellent vox populi journalism. Kind of a left field recommendation for this thread, but genuinely something that broadened my horizons by a lot.
