Plurk is a social networking site that allows you to work in real time with other people. For example, you add people to your Plurk group and then you can post a question to your page and live plurks will come back to you from other people on your network. It seems like it would be a great tool for teachers to network and share live and to use with students too. Plus it's a great alternative to Facebook. Try it: http://www.plurk.com
