Quality of content
Study: Wikipedia as accurate as Britannica.–Nature, 2005
● Claim has been disputed, but even being close is signifi cant.
● English Wikipedia has 8x as many articles in 2012 as in 2005.
● Proportion of Featured Articles (top quality, peer reviewed content) remains about 1/1000.
● Peer review process has become more rigorous, and found to be robust.
● International and multilingual focus has grown.

Quality of content
Study: Curious people use Wikipedia as scaffolding.
–Ed Chi, 2011
● Subjects were asked to research a topic.● Most spent a lot of time on Wikipedia in the
fi rst few minutes, later gravitating toward more thorough or more authoritative sites.

Peer production
Wikipedia construction guided by strong values.
The Five Pillars:● Wikipedia is an encyclopedia.
● Wikipedia is written from a neutral point of view.
● Wikipedia is free content that anyone can edit, use, modify, and distribute.
● Editors should interact with each other in a respectful and civil manner.
● Wikipedia does not have fi rm rules.
Talk pages: a key innovation
Readers and editors are invited and encouraged to discuss editorial changes, on a separate, but linked "talk page."
Example: Talk:Bicycle safety, 2005
Talk pages: a key innovation
Example from Talk:Bicycle safety, 2005:
I acknowledge that this [article] might contain elements of [bias], I have strong opinions. I aim to reference more of it in the near future. —JzG
Here's a suggestion… present one side as [unbiased] as you can. … I like the idea of presenting as many sides as feasible, and letting the reader decide. Informative over persuasive. --Christopherlin
Yes, you are right I know. … —JzG
Edit history: Perceiving activity
Software supports following actions of your fellow editors very closely.
Example: "Bicycle helmet" history page
Production: WikiProjects etc.
Analogous to a “talk page” for a topic area●WikiProject Medicine is a very active project●WikiProject Health & fi tness is not
●Many refinements to Featured Article system
Production: Further discussion
● Confl icts of interest (WP:COI)
