Just ask Apple investors whose stock lost 10 per cent of its value in 10 minutes after false reports that CEO Steve Jobs had suffered a heart attack hit the blogosphere ... Even the smartest people are easy prey. Verifiable facts, and even simple common sense, have little or nothing to do with the way a rumour spreads. Utterly improbable urban legends persist even though they can be easily disproven. And, of course, once a rumour finds its way to the web, it lives forever.
