I'm really interested in how these ways to game the system spread throughout a given market. I've referred to it as the "psychology of markets" and heard it called "behavioral economics." Could you recommend any other sources to read more?
I only recently started taking notes in my own books and already see the flaws with doing so. I like that you approached the problem with a more direct solution.
I wonder about future technology when PG says "Eventually we may be able not just to play back experiences but also to index and even edit them." I also wonder about the iterations between now and then.
What do you think could be an intermediate step (company idea) between your wiki and something like a searchable memory catalog that would do what PG describes?
