4. What is a wiki? What does Wiki mean? –Why for this use? How the software works. –Restrictions on participation. –Editing. –History pages. –Recent changes. –Search functions. What/who is a Wikipedian?

5. Norms A shared belief in Linus’ law, “Given enough eyeballs, all bugs are shallow.” –The more it is reviewed the better it gets. Neutral point of view. –Assert facts about opinions, but not opinions themselves. Verifiability –Against a reliable peer-reviewed source. Not original research. –Previously published by reputable source. –No novel historical interpretations.

6. Why it works Because it works for Wikipedians. –Committed effort. –Why do they do it? Wiki ettiquite. –Good faith. Civility. Discussion. –Dispute resolution.

Fostering the virtual cycle. –Personal satisfaction contributing to knowledge. –Friendship and teamwork. –Moving to new projects. –Allowing for multiple entries from many sources.

7. Contrast with a traditional encyclopedia. Sources for authoritative text. –“Self-selected” editors & contributors instead of experts. –Guarding against junk science. Topic selection. –Who assigns responsibility? –Consensus as arbiter? Framing passages. –Editors enforce consistency. –Forming the index for the whole. Tone and presentation. –Will one expert author consistently expressing a view beat contributions from all corners, melded by editors, others? –Emphasis on surprises, quirks, novelties, populism. What else?
