Well I really like @Castopod but their fediverse functionality is super limited at this point. Can't edit posts, can't tag accounts or hashtags. Anyway you can follow my Castopod account at @brooks to see what happens. I wish it would just upload the audio directly to my account like this so people can just click play and check it out.

These features are definitely in the roadmap but we don't have any ETA yet… Do not hesitate to provide feedback (or more…!) on https://code.castopod.org/adaures/castopod
Glad to hear it!
