My personal feelings are strongly anti-podcast. I find them a great inconvenience. I can read faster than people can talk and I can't think or work effectively when someone is talking. Written communication is by far my favorite way of getting information.
For users, not creators. They take a lot of work to do properly (Doug Kaye, The Secret Lives of MP3 Files, http://pa.gigavox.com/shows/detail1600.html mp3, 54min, 25Mb ) and besides articles are way more bandwidth efficient given their size.
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.
Not even for the founders dinner speakers? Looking Forward to Jessica's blog. I am about to finish her book.
