"The user who visits Wikipedia to learn about some subject, to confirm
some matter of fact, is rather in the position of a visitor to a public
restroom. It may be obviously dirty, so that he knows to exercise great
care, or it may seem fairly clean, so that he may be lulled into a false
sense of security. What he certainly does not know is who has used the
facilities before him."
