Really glad to hear that you found the post interesting and/or useful--and really excited to see whatever you come up with, whenever you come up with it.
We definitely agree that discovery and complexity are necessary, and that the goal would be simply to avoid the forms that they conventionally take in Berlinier roguelikes. Likewise, I love the idea of randomizing elements other than dungeons and potions (or dungeons and potions by other names, for that matter). Like you say, lots to chew on.
Thanks again for inviting me to talk!
