There are so many great ideas on this wiki. I added mine - that I have used a wiki to honor a long-term teacher, and allow former students to contribute - and that I am using one to organize a conference. I love the collaborative nature of this tool and just wish more people would contribute so that I can truly see how well it works. Ah, well.
I have read through much of Joyce Valenza's School Library wiki - and find her powerpoint presentation very helpful. I was also pleased to read a recent Newsweek article, on the way in which are becoming more commonplace in the workforce. I thank Will Richardson's blog for that information. I truly believe that, if we can get more comfortable with this tool, it will be an asset in ways we cannot yet imagine.
