I meant this relating to time. It takes a long time and a couple of revisions to write a good polished essay (or blog post) I think for creating a podcast you write down what you want to talk about in point form and then you talk and elaborate on these ideas.
That would be the equivalent of writing down a few notes for your essay beforehand and then posting the first draft. The revisions are needed for a reason, which doesn't go away if you're talking instead of typing.
