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.
Users can doodle while commenting, use multiple identities, and pick which comments are shown through moderation. VoiceThreads can even be embedded to show and receive comments on other websites and exported to MP3 players or DVDs to play as archival movies.
Disqus, pronounced "discuss", is a service and tool for web comments and discussions. The Disqus comment system can be plugged into any website, blog, or application.

Our idea is to help you tell better stories online using photos.
You can create a rich slideshow in seconds to engage your friends or family in a natural way. This is done by allowing two-way commenting right at each photo in the show and automatically pausing so you have time to express yourself before continuing.
We also support zooming comments, sound-effect smilies, and music so you can elaborate on your story further.
