:science-fiction fandom:: n. Another voluntary subculture having a
very heavy overlap with hackerdom; most hackers read SF and/or
fantasy fiction avidly, and many go to `cons' (SF conventions) or
are involved in fandom-connected activities such as the Society for
Creative Anachronism. Some hacker jargon originated in SF fandom;
see {defenestration}, {great-wall}, {cyberpunk}, {h},
{ha ha only serious}, {IMHO}, {mundane}, {neep-neep},
{Real Soon Now}. Additionally, the jargon terms {cowboy},
{cyberspace}, {de-rezz}, {go flatline}, {ice},
{phage}, {virus}, {wetware}, {wirehead}, and {worm}
originated in SF stories.
