VoiceThread

"With VoiceThread, group conversations are collected and shared in one place from anywhere in the world. All with no software to install.

 A VoiceThread is a collaborative, multimedia slide show that holds images, documents, and videos and allows people to navigate pages and leave comments in 5 ways - using voice (with a mic or telephone), text, audio file, or video (via a webcam). Share a VoiceThread with friends, students, and colleagues for them to record comments too."

Any recommenders out there?
