Wow, this looks a cool idea. Found the link in the John Johnston’s notes for his lecture on podcasting. John is a primary school teacher in Edinburgh, UK, who is doing some interesting things with audio and podcasting.
I listen to podcasts, but I haven’t ventured into podcasting myself. Of the 200 or so of my students this year, I only know of 2 who are actually blogging, so at this moment I don’t the extra work would be worth the candle. Tho I feel like trying just so that I can say “I can podcast!”
