Thanks for summarizing important points on wikis and I am also looking forward to seeing your final project, the wiki chapter. Wikis are really good activities to individually create edit and design online contents and specific topics. Also, they provide users to learn and work collaboratively. As you said, wikis encourages people to write, and participate in group projects. Also, I think motivation is important to make students to participate in wikis projects. I agree with you on the challenge of wikis, which should take instructional design for wikis into consideration.
