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.

    noviembre 9, 2009

    The following tables compare reference management software.




    In the “notes” section, there is a difference between:

    • web-based, referring to applications that may be installed on a web server (usually requiring MySQL or another database and PHPperlPython, or some other language for webapps)
    • centrally-hosted website

    el esquema, el Id, y el id 2.0

    noviembre 4, 2008

    Pensando en el tema del “id 2.0” y el video de Dick Hardt, es decir, sí esto funciona así, parece que la red que tengo aquí con éste blog, es mi identificación en Internet, la sociedad de la información o diría Castells la “galaxía internet”, en mis notas iniciales viene explicado de manera general, la forma en cómo esta estructurada mi red. Observamos que en ese esquema, aparecen distintos conceptos, existe uno importante, que tiene que ver con nuestras identidades y datos que hemos construido en la red, En el esquema que he propuesto le llamo “Id”, en la presentación “The future of social networks on the internet: The need for semantics” de John G. Breslin, mencionan el termino,  “Single global identity”, con los terminos FOAF, hCard, OpenID. Es interesante, pero pienso tambien ¿quién y para qué? y ¿para donde vamos con la gestión de las identidades? ¿los derechos que tengo de decidir quién va a administrar mi identidad, con mis gustos, con mis creencias y mis prácticas en la sociedad de la información?

    Interesante será donde firmamos, el papel de los gobiernos, las instituciones, las universidades y las empresas….

    En el cámino andamos y aquí les dejo estos links.
