Wiki's are great! They seem to be everywhere now, which is amazing to me since before August I had not ever heard of them. They are a great way to collaborate and share ideas with fellow teachers. My campus has a wiki that we use to share resources and great lesson ideas, as does our Campus Lead Teacher group. I could see this being a great resource to use over the summer as a teacher. Teachers can collaborate and plan with eachother, while being able to do it on their own time. I would also love to set up a persoanl wiki to plan a family reunion for this summer!
