There’s a small downside to having a podcast running on your main Micro.blog subscription. If you submit your podcast to Apple Podcasts (or anywhere else), Micro.blog by default defines your podcast title and artwork based on your blog. So your blog title is the podcast title, and your podcast artwork is your Micro.blog photo.
Manton plans to add the ability for everyone to change the podcast title and artwork in the Micro.blog dashboard at some point in the future. Until that feature is available, you can make the changes yourself if you’re using a custom theme.
