The process of making a piece of knowledge suitable for space repetition is a lot about making the piece of knowledge as clear as possible.
When it comes to my own writing, I don’t think it discourages me to write about ideas I believe are worth writing about that this new feature exists. I might find it interesting to experiment with a new way of writing posts and use the feature, but I don’t believe that this is zero-sum.
Asking “Is this likely to be useful?” is the wrong question. I think it’s better to ask: “Is this an experiment that has the potential to produce something useful for the art of rationality?”
Trying out new ways to represent knowledge about the art of rationality has the potential to lead to progress and is thus worth doing. We shouldn’t try to focus on one approach of gathering knowledge about rationality but try many.
