Show HN: Learn/teach advanced topics with blackboard videos

It's like KhanAcademy + capitalism. Learners pay $10 upfront to request teachers for ANYTHING advanced they want to learn (e.g. post-graduate math, SWE technologies e.g. AWS, Svelte). Teachers use iPad + stylus to draw & talk & record blackboard videos.

For teachers, you can teach flexibly, at small-scale to an all-paying, engaging community, or achieve economies-of-scale with where income scales O(n) but time-required only scales O(logn)

For students, it's WAY cheaper than tutoring, with little sacrifice to personalization as you ask questions directly and still have option to 1-on-1 when absolutely necessary
