"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]
