This is my site of the day (maybe the week):
QWIKI sorts results into relevant bits and then via text to speech gives an overview of the topic. It is easy to use and will further delve into the topic with deeper Qwikis. A great way to get students started on a topic. This is their alpha release and they are collecting all types of inputs to make this new tool better.
Consider giving it a “qwiki” test drive.
