Lurker

A lurker is a member of an online community who reads, watches, and follows the conversation but rarely or never posts, comments, or otherwise contributes content. The term has been part of internet culture since the early days of forums and Usenet, where lurkers were described as the "silent majority" who observe a group's discussions without participating. Lurking is not inherently negative—newcomers are often advised to lurk first to learn a community's norms before jumping in—but it does mean the visible, vocal portion of any community represents only a small slice of its actual audience.

This dynamic is captured by the well-known "1% rule" (or 90-9-1 rule) of participation inequality: in many online communities roughly 90% of people only consume content, about 9% contribute occasionally, and around 1% create the bulk of new material. On Reddit, lurkers are believed to vastly outnumber active posters, and many people browse, read threads, and even vote without ever commenting. Their presence matters because it shapes how representative discussions really are—the loudest accounts may not reflect the silent majority—and it affects how communities measure engagement, since view counts and traffic dwarf the number of contributors actually shown on screen.
