Having spent a week or so among Twitterzens, I can say with assurance one thing. It is the single greatest showcase of logical fallacies ever invented. Political pamphlets of any century have nothing on Twitter. Admittedly, the (extremely) short character limits mean that the platform does not lend itself to deep thought. Moreover, following more than, say, ten people, means that one's tweets are quickly mowed down by more tweets.
However, the sheer volume of logical fallacies evidenced in Twitter seems less the fault of the platform, and more a fault of...well, just about everyone on it. I have, without doubt, been occasionally guilty of logical fallacy. But, I mean, really.
