Economist and blogger Tyler Cowen on Berlin:
Berlin is evidence that most tourists don't actually care so much about history, culture, and museums, as it is not for most people a major tourist destination, despite having world-class offerings in each of those areas. Mostly tourists like large, visually spectacular sites, or family activities, combined with the feeling that they are taking in culture or seeing something important.
Now if I said something like that...Another observation:
There are, however, a fair number of Russian tourists who enjoy the nostalgic feeling they get walking through the eastern part of the city and visiting communist monuments and sites.
