I completely agree - at the moment I'm focused on getting feedback from "tech savvy" early adopters, so I thought this description might help express what I'm going for most effectively here on HN. But once I nail down the features that make sense for buildings and real estate, I'm hoping I can come up with a more approachable way to describe the functionality (even though I would like to incorporate and build on the more sophisticated concepts that GitHub has made pretty standard for code.)
