On Biz Podcasting, I've talked about the many attempts -some good, some bad - that educators have...well...attempted with podcasting. There are more digital audio players in the hands of the world today than last there was at the beginning of school last year, and we've seen many schools announce that they'll be using podcasting as part of the curriculum. Apple has published a tutorial on how to use podcasting (link, anyone? Lost it...) to education and the stage is truly set.
Keep an eye out over the next few weeks for new educational podcasting initiatives. I think there will be a few that we didn't see coming.
