I would like an educational presentation to be in a text format rather than in a fast-moving audio presentation. The reason is that with informative stuff, sometimes it is useful to slow down the data rate to more totally understand the material, and possibly even to repeat a bit of it. For worthless entertainment and comedy a steady rapid-fire delivery is OK, but for worthwhile subjects that I can actually gain something from, text is better. AND, if I had considered this presentation worthless that would not bother me. But it did seem worth while and so not having it in text is a bother.
