Slashdot was originally created in September of 1997 by Rob "CmdrTaco" Malda. Today it is owned by Geeknet, Inc..
Slashdot is run primarily by me and a handful of other others, who post stories and wrangle the day-to-day affairs of Slashdot.
Slashcode is wrangled and various other deeds of a technical nature are committed by Slashteam: Jamie McCarthy, Chris "Pudge" Nandor, Wolf, Chris Brown, and Tim Vroom.
Editorial responsibilities are still handled by Rob "CmdrTaco" Malda, along with the rest of the Slashdot Authors: Timothy Lord, Patrick "Scuttlemonkey" McGarry, Jeff "Soulskill" Boehm, Rob "Samzenpus" Rozeboom, and Keith Dawson.
