Bohemian culture 'is now the norm' or is it?

Fascinating article claiming that we are pretty much all the cultural inheritors of the bohemians: it was their 'wierdness' and protest and willingness to not conform that have ehlped create the informal, first-name, dress-down society we now know and [usually] love. If it were true it would be a salutary lesson in the power of small actions when promoting an idea whose time has come. But it's an 'if' there: what of the American west and the cultural process of 'bohemian' change from that that has affected the English-speaking [no, more] world? If indeed it is the American west we attribute it too. Any American want to comment?
