The Twitter Archive at the Library of Congress: Challenges for information practice and information policy | Zimmer | First Monday
"In April 2010, the U.S. Library of Congress and the popular micro-blogging company Twitter announced that every public tweet, since Twitter’s inception in March 2006, will be archived digitally at the Library and made available to researchers. The Library of Congress’ planned digital archive of all public tweets holds great promise for the research community, yet, over five years since its announcement, the archive remains unavailable. This paper explores the challenges faced by the Library that have prevented the timely realization of this valuable archive, divided into two categories: challenges involving practice, such as how to organize the tweets, how to provide useful means of retrieval, how to physically store them; and challenges involving policy, such as the creation of access controls to the archive, whether any information should be censored or restricted, and the broader ethical considerations of the very existence of such an archive, especially privacy and user control."

Why Twitter Should Not Algorithmically Curate the Timeline — The Message — Medium
"There is so much Twitter can do try to improve the user experience, for both the experienced and the beginner. But I hope that it does not algorithmically curate the feed, not because I love the chronology per se, but because I value people’s judgement. Yes, Twitter can make it easier to access that judgment in more varied ways but stepping between people I choose to follow and me is not the answer."

[1304.3480] Friendship Paradox Redux: Your Friends Are More Interesting Than You
"Feld's friendship paradox states that "your friends have more friends than you, on average." This paradox arises because extremely popular people, despite being rare, are overrepresented when averaging over friends. Using a sample of the Twitter firehose, we confirm that the friendship paradox holds for >98% of Twitter users. Because of the directed nature of the follower graph on Twitter, we are further able to confirm more detailed forms of the friendship paradox: everyone you follow or who follows you has more friends and followers than you. This is likely caused by a correlation we demonstrate between Twitter activity, number of friends, and number of followers. In addition, we discover two new paradoxes: the virality paradox that states "your friends receive more viral content than you, on average," and the activity paradox, which states "your friends are more active than you, on average." The latter paradox is important in regulating online communication. It may result in users having difficulty maintaining optimal incoming information rates, because following additional users causes the volume of incoming tweets to increase super-linearly. While users may compensate for increased information flow by increasing their own activity, users become information overloaded when they receive more information than they are able or willing to process. We compare the average size of cascades that are sent and received by overloaded and underloaded users. And we show that overloaded users post and receive larger cascades and they are poor detector of small cascades."
