Thanks it's hard to find time to do 30 minute calls as this is a glorified side project, but I actually had the same idea and recorded some calls with customers for public consumption as I thought might improve some of this communication, but I never got around to editing it and wasn't sure if the content would be compelling.
Definitely feels like some form of video might be superior vs email, which is easiest in some ways but also seems to be a bit of a barrier in thoughtful communication.
