The post is interesting, and four years old... so what has changed in Hest since then?
I spent the following year exploring the space with a handful of prototypes, and then recorded a series of podcast episodes as a form of design journaling: https://ivanish.ca/hest-podcast/ Work on Hest continues, but I'm being quiet about it until I have something to show.
Cool, you have a very nice mic. Great sound quality on the recordings. That gives me a few days of listening material. I liked the brief glimpse of Hest in the end of the Jack Rusher talk at Strange Loop, looking forward to find out a bit more about what you're doing.
