The internet's perfect for all manner of things, but productive discussion ain't one of them. It provides scant room for debate and infinite opportunities for fruitless point-scoring: the heady combination of perceived anonymity, gestated responses, random heckling and a notional “live audience” quickly conspire to create a “perfect storm” of perpetual bickering.
