For what it's worth, let me encourage anyone who posts a lecture or podcast online to also post a transcript. Perhaps I'm a dinosaur, but I rarely sit through lengthy video or audio presentations. I haven't the time and I don't see the point of listening to something that I could read much more quickly, and I doubt that I'm alone in feeling this way. But I do read online papers and transcribed podcasts. So if you are presenting from a written text, posting the written form as well could enlarge your audience.
