#19 Discovering Web 2.0 tools

I discovered Meebo.  At first I thought this would work great for online reference, but then, as I understand it, you can have many people in the room at the same time.  So I guess regular IM would work better there, since you would have a separate window for each patron.  I think it is going to take me quite a while to figure out what is possible here, especially since my computer has a very flaky internet connection right now.  So far I have only received offline messages.
