Facebook operates at a different intellect level to HN. A friend spends a lot of time on Facebook and, whenever she wants to tell me some fact or a joke I always ask 'is this a Facebook joke/fact?'. Clearly if it is a 'Facebook joke' I won't find it funny, I will just have to suffer boredom, hence I ask first so I can be prepared for some soul destroying trivial nonsense. In social networks there is a sort of recommendation from a personal friend that comes with stuff. So, some mis-fact-rumour just has to get past that threshold of convincing-ness, thereafter it can go on viral. Some rumours start as one story that gets mis-interpreted and then it spreads, there is nothing that the original source can do about it. We all do it '640K RAM, enough', 'Al Gore, invented the interwebs' and so on...
