Slashdot, often abbreviated as /., is a science, science fiction, and technology-related news website which features user-submitted and editor-evaluated current affairs news with a "nerdy" slant. It is known for the Internet forum-style comments section attached to each story; Slashdot was one of the first popular websites to include a commentary section in such a prominent manner.

The summaries for the stories are generally submitted by Slashdot's own readers with editors accepting or rejecting these contributions for general posting. While Slashdot's haphazard editorial style produced a unique voice in the pre-blog age, users frequently post criticisms of perceived arbitrary or biased editorial choices.[citation needed]

Though the site antedates the modern concept of the weblog, Slashdot's architecture is commonly compared to that of modern blogs. Slashdot is notable in that its commenting system is much more robust than most blogs, with threading and user moderation having been introduced before these were commonplace in modern weblog packages.

Officially, the name "Slashdot" was chosen to confuse those who tried to pronounce the URL of the site.
