The next speaker at AoIR 2009 is Karine Barzilai-Nahon, who shifts our interest to network gatekeeping theory. Online, users can become gatekeepers, and are no longer simply being gatekept for - so gatekeeping power has shifted to some extent; additionally, gatekeeping is no longer a solid state, but is becoming a much more dynamic phenomenon where we're sometimes gatekeeping ourselves, sometimes receiving the results of gatekeeping processes.
Gatekeeping theory was developed by Kurt Lewin in the 1940s, observing food habits in families (and seeing housewives as gatekeepers at that time); this was later applied in a major way to the editors in news publications, who control what information is selected for publication from all the daily events. Other applications are the management of technology (what new technologies reach a larger range of users) and information science (already starting to look at the role of communities as gatekeepers).
