yeah, for sure. i think the diagrams/artifacts are definitely more ephemeral, since they fall out of date. in my experience, the more lasting artifacts from the whiteboarding session have been
1) making the code that ships higher quality because i understand it, and
2) getting my own mental model aligned with the current state of the codebase.
we're dreaming up some features in a hosted version of the product which could maintain an up-to-date 'software map' of your codebase, and that is the backbone which would power all diagrams/visualizations
