I would expand on that point. Britain (England?) has a very strong class-based culture (in fact I read Hindu India's present system of four castes is a colonist creation, with the Brits classifying and grouping hundreds of clans into castes modelled on British society) that is intimately tied to language. Which doesn't just mean dialects and mannerisms that are more class-based than locality-based, but discussions that are less about exchanging thoughts about subjects than about reinforcing community by regurgitating the same memes that can be safely assumed to be shared. Such behaviour is of course far from being specific to the subcultures of classes in England, but never do I get as strong a sense of posters engaging in social confirmation with second-hand talking points rather than expression of own thought than when viewing discussion forums of British media.
