I share your interest in a rationality and life-hacking house. I'd like to coordinate with you on that, if only to help see that it happens. I wonder how it might intersect with my friend's interest in creating a neighborhood of "Tiny Houses"--affordable and economic housing, that definitely forces you to be aware of all your stuffs' utility.

Also think programming of rationality exercises is a good idea. I've been ruminating on the idea of starting a less intensive but more long-term version of minicamp in my area, that I've in good humor dubbed "Nanocamp". Online practice exercises is one way to keep lessons consistent and progress trackable.
