Not a clubhouse expert but it seems clubhouse is better for “spontaneous” conversations/talks, as in I don’t have to upload it as a podcast perhaps do post-processing etc to get my content out.
It also allows you to promote your audience to speakers so it’s more of an interactive podcasts, so you can actually ask questions to a panel or the speaker.
Again, haven’t used it much but this is what I understand Clubhouse brings to the table.
