I was wondering whether podcasting had gone Web 2.0. And sure enough, there's a lovely New Zealand site, BigPod.co.nz, where you can make and publish podcasts without having the necessary software on your own computer. BigPod asks politely whether it can access the microphone (and camera if you have one) on your own computer. Within seconds I created a memorable audio file and made it available to the world.
Then I deleted it. The content: a sweetly sung testing testing testing ... I didn't test the editing facility. Naturally as an alternative you can upload your own audio and video files, but the BigPod system is exquisitely simple.
