Interesting discussion going on about podcasting. As always, the truth is probably somewhere in the middle. People who have long(ish) commutes, esp. in a car, I think will really embrace podcasts as they become more discoverable. But Peter is also right – they are massively inefficient compared to reading. I think there is a software solution out there that allows people to speed up voice recording w/o changing the tone – that is one answer, because the ear can process words faster than the mouth can deliver them. And Robert, go ahead and read you r smartphone when you are walking around, but not when you are driving please!
