Learnt about this site at NV08, VoiceThread. In 5 minutes was able to put this amateur picture, comment and doodle about the new ATM that was installed at the credit union. Please forgive the message, it is the medium that is intriguing.
A trial with VoiceThread
Tinfoiling 
I am collecting examples of how educators are using Voicethread in their classroom or for professional development on a wiki at: http://voicethread4education.wikispaces.com/
My plan is to share these examples with other technology teachers who provide professional development in their schools.
Feel free to add your own examples or links to resources. Thanks in advance,
Colette
