The impact of web 2.0 on research practices

Social academia
Since the emergence of the web 15 years ago, information
and communication technologies (ICTs) have become
indispensable for most researchers. Email and online access
to public or restricted databases have become essential
tools, allowing academics to keep in touch with their peers
and up to date with the latest developments. Widely
dispersed research groups can now easily coordinate their
work online by means of Skype conference calls.
   Within some sections of the academic community there
is considerable hesitation to adopt web 2.0 applications for
social networking through blogs, wikis, twitter and sites
such as Facebook and YouTube. Granted, some academics,
including a few professors, now write personal blogs, but in
general, researchers seem reluctant to enter the realm of
social networks, and to start using web 2.0 tools for
producing collaborative reports, sharing work in progress or
publishing their results.
   There are perhaps three major obstacles. First, the formal
system of peer review to guarantee the quality of research
is at odds with the informal and much more open ways of
communicating via online social networks. The second
obstacle is the ‘publish or perish’ rule – researchers must
publish in peer-reviewed subscription journals in order to
further their academic careers. This does not fit well with
philosophy behind social networking that all knowledge
should be freely available. Finally, the ambition of all
researchers to publish their findings before anyone else, and
to secure potentially profitable intellectual property rights,
discourages them from sharing work in progress on
platforms that are open to all.
   In this special report, Janelle Ward examines two web 2.0
applications, blogs and wikis, that are slowly gaining
acceptance among academics. The Broker wishes to open a
discussion on the processes of generating and publishing
knowledge in the web 2.0 era. In particular, The Broker will
address whether the principles and applications of web 2.0
could contribute to greater inclusion and higher-quality
research or represent a distraction that may dilute the
quality of research, and whether a divide is in the making
between researchers of the web 2.0 generation and the

academic establishment.

     The challenges of social media

     Rewriting research
     A growing number of academics are using web 2.0 tools such as blogs
     and wikis to share their findings, discuss new developments, and find
     new ways for collaborative research. How does this open and informal
     medium fit with traditional academic processes? Although there are still
     some significant hurdles to be overcome, as well as doubts, web 2.0
     represents more than just a new technology. Its widespread use,
     including by academics, may offer solutions to many existing problems,
     as well as open up new prospects for communicating research.
