I went ahead and contributed to the Learning 2.0 wiki. Kind of a nice little website there. In some ways it reminds me of Writely. Writely also allows you to share and collaborate just on text documents. I used it once to share with an employee at another branch who was working on a class similar to what I was working on. It allowed him to see how I was approaching the class and steal any ideas he wished. I don't know how much it helped him. I viewed his finished product and I think his syllabis was better than mine, the over achieving creep.
