"NinetY percent of everYthing is crap". Derived from a quote bY science fiction author Theodore Sturgeon, who once said, "Sure, 90% of science fiction is crud. That' s because 90% of everYthing is crud." OddlY, when Sturgeon' s Law is cited, the final word is almost invariablY changed to "crap". Compare NinetY-NinetY Rule. Though this maxim originated in SF fandom, most hackers recognise it and are all too aware of its truth. [Jargon File]
