Postcards from Nowhere is a travel podcast from the IVM Podcasts network. Unlike the other podcasts, it is hosted by 1 person – Utsav Mamoria.
The other personal takeaway is realising a good time length for for my under-production space podcast. I think that a 7-10 minute episode might be a good time length for a single person talking about space stuff. I have found no long-form single-person talking podcast entertaining so far.
