Nino Kerl runs ninotakutv, a hugely popular German anime YouTube channel with over 392k subscribers. Beyond YouTube, he's built out a whole ecosystem around anime fandom: his website ninotaku.de functions as a fan-run online magazine, he picks up voice acting work on the side, and he's also written a novel called "Herz aus Stern" (Heart from Star). He describes his website pretty straightforwardly—it's by fans, for fans.
