There's a New Kid in the Hall #edtech

I only have a few minutes to get out this post, so I'm going to keep it simple.  Hall is a simple mashup that combines many web 2.0 tools into a powerful collaborative force. At the surface it is a chat room that keeps a record of all activity.  But, it's the four integrated applications that make Hall special.  A poling tool, ranking tool, a to-do app and a collaborative notepad that can be attached to the chat.  You can invite people to join your room via email, Facebook and Twitter.  This may be just the walled garden for which a lot of you have been searching.
