The idea: what if you could get a “Masterclass”-style experience, but free, using existing YouTube content?So I made OpenCademy — right now it only has two quick startup "courses" (101 & 102), built from curated YouTube clips, all embedded and organized into modules.It’s still early (no accounts, no backend), but it’s bingeable.Would love thoughts on whether this concept feels useful or just... redundant.
