Hi there.
Heather Ross from Saskatoon here. I've been fortunate enough to be involved in three podcasts thus far and am looking forward to many more.
I think that podcasting is already playing a significant and growing role in education:
- Students are trying it out just as they have video, newspaper and other forms of media production in the past.
- Educators are using it to share their lectures.
- Many involved in education are podcasting about educational issues.
I think that podcasting is making it easier to provide new venues for informal learning. I can listen to a podcast of a history lecture from an institution in another country. In some cases I can listen to entire courses worth of lectures. Podcasting is also making it easier for educators to share ideas through their own podcasts (as I mentioned above).
As for your last question, Richard, what are the dangers ... right off the bat I think that podcasting has grown so quickly we may be looking at backlash from some powers-that-be as we've seen with attempts at blocking and censoring social networking Web sites.
Anyway, this is just my pre-coffee two cents.
