Your observation about the differences between markets is a massive factor that people usually overlook. In western markets, especially on platforms like LinkedIn or TikTok, distribution relies heavily on building a distinct persona or a hyper specific angle rather than just relying on the algorithm to find an audience for a piece of media.
When you automate everything, you lose the cultural context and the fast feedback loop needed to tweak things for western audiences. A lot of successful distribution here comes down to taking one core idea and manually reframing it for three different subcultures, which requires understanding the specific slang, pain points, and memes of those groups.
Since you mentioned the Korean market works differently, I would love to hear what the biggest differences are in how platforms serve content there compared to what you are seeing in English markets.
