Hey wiki researchers,

My team at the Wikimedia Foundation, now including Aaron Halfaker who many of you know, is embarking on work this year to try and engage more anonymous editors. Particularly with an eye toward showing them the benefits of registering an account.
 
Where I need your help is this: what are the best papers you know that focus on anonymous (IP) contributors? Your collective understanding of the literature here is far greater than mine. I'll be combing through the archives of the Wikimedia Research Newsletter, but I'd greatly appreciate any choice recommendations, sent to me off-list if that works for you. 

Many thanks,
