This is an interesting looking tool. Might be easier to use than podomatic to create podcasts. You can embed or link to the voicethread you create. One downside I can see is that you have to record via the macromedia recorder on the website. My experience of this in podomatic is that the quality isn't that great. Also it requires a microphone plugged in. I have been giving my iPod with attached microphone to the kids to record podcasts for our class. We also use audacity to manipulate the audio and get rid of all the umms and ahhhs and hesitations. I'd say it is worth looking at but I'd like to see them add some audio editing tools like jumpcut provides for video.
