“90-9-1” Rule for Participation Inequality: Lurkers vs. Contributors in Internet Communities Jakob Nielsen’s Alertbox

enero 9, 2010

Jakob Nielsen’s

Alertbox, October 9, 2006:

Participation Inequality: Encouraging More Users to Contribute Summary: In most online communities, 90% of users are lurkers who never contribute, 9% of users contribute a little, and 1% of users account for almost all the action. All large-scale, multi-user communities and online social networks that rely on users to contribute content or build services share one property: most users don’t participate very much. Often, they simply lurk in the background.In contrast, a tiny minority of users usually accounts for a disproportionately large amount of the content and other system activity. This phenomenon of participation inequality was first studied in depth by Will Hill in the early ’90s, when he worked down the hall from me at Bell Communications Research see references below.the 90-9-1 rule for participation in an online communityWhen you plot the amount of activity for each user, the result is a Zipf curve, which shows as a straight line in a log-log diagram. User participation often more or less follows a 90-9-1 rule:

  • 90% of users are lurkers i.e., read or observe, but don’t contribute.
  • 9% of users contribute from time to time, but other priorities dominate their time.

  • 1% of users participate a lot and account for most contributions: it can seem as if they don’t have lives because they often post just minutes after whatever event they’re commenting on occurs.

    Getting started with Qualitative Data Analysis SoftwareBelow are links to materials that tell you how to undertake some of the basic activities in qualitative data analysis software such as importing documents and starting projects, coding and its organisation, creating memos, text and code searching, reporting and retrieving information.Many software developers now produce their own teaching materials that cover the basics of the software use. Where this is so the links below are to their materials. In other cases there are links to materials on this site that cover older versions of the software to help those who are still using these versions.

    Delete – The Virtue of Forgetting in the Digital Age

    noviembre 12, 2009

    Book: Delete – The Virtue of Forgetting in the Digital Age

    Delete looks at the surprising phenomenon of perfect remembering in the digital age, and reveals why we must reintroduce our capacity to forget. Digital technology empowers us as never before, yet it has unforeseen consequences as well. Potentially humiliating content on Facebook is enshrined in cyberspace for future employers to see. Google remembers everything we’ve searched for and when. The digital realm remembers what is sometimes better forgotten, and this has profound implications for us all.

    In Delete, Professor Mayer-Schönberger traces the important role that forgetting has played throughout human history, from the ability to make sound decisions unencumbered by the past to the possibility of second chances. The written word made it possible for humans to remember across generations and time, yet now digital technology and global networks are overriding our natural ability to forget–the past is ever present, ready to be called up at the click of a mouse. Mayer-Schönberger examines the technology that’s facilitating the end of forgetting–digitization, cheap storage and easy retrieval, global access, and increasingly powerful software–and describes the dangers of everlasting digital memory, whether it’s outdated information taken out of context or compromising photos the Web won’t let us forget. He explains why information privacy rights and other fixes can’t help us, and proposes an ingeniously simple solution–expiration dates on information–that may.

    Professor Mayer-Schönberger’s new book, “Delete – The Virtue of Forgetting in the Digital Age”, published by Princeton University Press, is hot off the press and now available at online and offline bookstores, including at Amazon.

    Can We Reinvent the Internet? — Mayer-Schönberger 325 (5939): 396 — Science

    SOCIOLOGY:

    Can We Reinvent the Internet?

    Viktor Mayer-Schönberger

    Recently, researchers who support “network neutrality” have become worried that the Internet may lose its innovative edge. They are concerned that control could be shifting from the edges of the Internet toward the service providers at the center, which would allow the providers to have “gatekeeper” capacity and would contradict the Internet's “end-to-end” principle (1–3). This core tenet states that control over information flows should take place, to the extent possible, at the end points of the network (4). President Obama supported net neutrality during his campaign (4) and in recent statements (5), and the European Parliament has added net neutrality to its recent telecom bill (6). Taking the end-to-end principle from protocols to users, Jonathan Zittrain has called for maintaining the Internet's “generativity,” the ability of users at the network's end points to create, distribute, and run whatever software code they choose (7). There are good reasons to preserve network neutrality and generativity, but it is unclear whether these are sufficient to ensure continued innovation. The larger issue is what policies are optimal to foster innovation on the Internet?

    Its main features are:

    * Graph Visualization

    * Global and Local Filters (enabling specific views on a graph)

    * Full text Search

    * Generating views from RDQL Queries

    * Visualising multiple RDF files

    RDF Gravity is implemented by using the JUNG Graph API and Jena semantic web toolkit.

    THE JOURNAL OF APPLIED RESEARCH AND TECHNOLOGY

    Instructions for Authors

    The Journal of Applied Research & Technology (JART) is indexed in the Science Citation Index Expanded and it is published three times a year. High quality original papers on innovative applications of science, development of new technologies or efficient engineering solutions are welcomed.

    Each submitted paper is subject to meticulous review procedure performed by three independent anonymous referees appointed and coordinated by the Editor-in-Chief. Their comments are communicated to the author in order to help him to improve the article and at the same time are forming the base of the publication decision made.

    The process of the article submission and its consequent evaluation as well as the communication among the Authors, Referees, Editorial Board and Editort-in-Chief, as well as with JART Staff, is highly automated by using online Internet services.

    Nevertheless the whole editing could take up to six months without considering the publishing process. To avoid delay in processing your paper, please be guided by the following guidelines for the Manuscript preparation as well use the electonic templates that are available at http://cibernetica.ccadet.unam.mx

    The processes for editing and publishing in JART are divided into two phases: Phase 1 that consists in sending the manuscript by the Author(s) and the consequent process of its review, improvement and acceptation or rejection, and Phase 2 dedicated to the publication procedures of the accepted paper.

    Digital Habitats Community Orientation Spidergram Activity

    Published by Nancy White under Communities of Practice, Orientations, Resources

    Cross posted from Nancy’s Blog

    A couple of people have asked me for more materials related to the Community Orientations Spidergram activity. I have embedded them into some slides now up … Digital Habitats Community Orientation Spidergram Activity.

    Here is a hint I should have shared earlier. The “context” orientation is a bit odd on the spidergram. You need to decide if internal orientation is in the middle/exterior towards the outside or reversed. I tend to use internal towards the middle, but I realized my instructions weren’t so clear.

    Another way to do it is to ignore the “context” spoke from an internal/external perspective and then do one layer on the spidergram around your internally focused activities. Then with a different color, do another layer on externally focused activities. I’ve done this with a few test cases and it quickly showed that some communities which have both internal and external contexts have very different internal and external activities.
