He tried the usual solutions: YouTube tutorials (too passive), online forums (too toxic and competitive), and paid tutoring (too expensive).

Part 1: The Loneliness of the Long-Distance Learner In the autumn of 2018, a university student named Lin Wei sat in a cramped 24-hour study café in Taipei.

Revenue became a problem. Without VC money, they introduced a "Patron Pass"—a voluntary subscription for users who could afford it, which unlocked cosmetic tree skins and nothing else.
