I am interested in interesting conversations about bitcoin (that interest me anyway), I just find it pointless seeing the same old criticisms trotted out by people who think the're the first to cry Tulip or whatever and betray that they haven't quite grasped the implications of this technology that are worth considering for better or worse. As a social democrat I'd like to try and envision how mixed-economies and welfare states can thrive in a world of crypto-currencies, so excuse me if I tend to roll my eyes at those still not getting how a world economy can run on only 21 million units or express their offence at people having crazy money making schemes, as if this is only just now the invention of money and credit itself.
