Slashdot is a technology news and discussion website, launched in 1997 by Rob Malda under the tagline “News for Nerds. Stuff that Matters.” Its own FAQ describes it as “the oldest tech news and discussion site on the web,” running on open-source software whose name expands to Slashdot-Like Automated Story-Telling Homepage. For years it was the dominant gathering place for programmers, system administrators, and free-software advocates, and an early proving ground for community-driven news.
The site’s lasting technical contribution is its comment moderation system. Rather than relying solely on paid editors, Slashdot distributes moderation power to its readers. The FAQ explains that the system periodically grants eligible users “tokens,” and that accumulating enough tokens turns a reader into a temporary moderator who can rate individual comments up or down on a numeric scale. Readers can then set a display threshold to hide low-scored noise, an early, influential answer to the problem of signal versus noise in large public forums.
Tied to moderation is karma, a per-user reputation score. The Slashdot FAQ defines it directly: “Your karma is a reference that primarily represents how your comments have been moderated.” Karma rises when one’s comments are moderated up or a story submission is accepted, and it helps determine who is eligible to moderate, creating a feedback loop intended to put judgment in the hands of consistently constructive participants.
To guard against abuse of that power, Slashdot introduced meta-moderation, or “moderating the moderation.” As the FAQ puts it, meta-moderation “seeks to increase fairness by letting logged-in users rate the rating of randomly selected comment posts.” Established accounts review whether past moderation decisions were fair or unfair, and those judgments feed back into who keeps the privilege to moderate. The layered design influenced reputation and trust systems across the later web.
Slashdot also gave its name to a phenomenon: the “Slashdot effect,” the traffic surge that overwhelmed a small website when it was linked from the front page. In an era before content delivery networks were commonplace, being “slashdotted” routinely took servers offline, an early demonstration of the load that a single popular aggregator could direct at the rest of the internet.
