According to a Yougov poll, 64% of Britons believe Wikipedia tells the truth "a great deal" or "a fair amount."
The BBC scored 61%, while The Times and The Guardian got 45%. The Sun and other tabloids scored 13%. The research was cited by Jimmy Wales during last weekend's Wikimania conference (Wikipedia scored well against the Encyclopedia Britannica for trust).
