Zapping has nothing to do with the content you're exposing yourself to. What you're looking for is an algo that would do the job of finding topics you like, which no one is stopping you from building for yourself.

That's my point is that people who care about zaps are missing what actually matters. The process of trying to understand a belief or a topic in the first place. A person who is wants to understand can't tell what is helping their understanding and therefore can't incentivize helping their understanding. Zaps will always be a distraction from what really matters.
