Ning
Ning is a place where you can create your own "walled garden" type of social network. Here, members can post blog entries, embed widgets, etc. in a protected environment that can be completely sealed from the outside.

You may consider this for a place to allow students to do internal posting of their work and/or commenting on the work of others.














Shelfari
This is a bookworm's dream! This social website allows you to track the books you have read, are reading, and want to read. Other members can make comments about books on your shelf or recommend other books to read based on your selections. This has one of the best graphical interfaces out there!

Take a look at My Bookshelf!











Pal Bee
Free live videoconferencing. Right now, all videoconferences are public, but the site says privacy controls will be added soon. Keep an eye on this one- nothing to install and easy to use!


















FreeConferenceCall.com
Just what it says- free phone conferencing (long distance charges may apply). It will record your conference and store it on their site for playback using a private access code. The recorded call may also be downloaded.














Cover It Live
Live blogging! That's right- text streams to your viewers much like a one-way IM but also allows comments and questions on the side. You can also add video, images, polls and audio files live on the fly. And when it's over, users can replay it! You may link to or embed your live session. Viewers need to download nothing!
