Thanks for the input. I believe that promotional material should always make sense. Of course they all point to actual cities/places that accept bitcoin. The goal was to show that bitcoin is popping up everywhere.

I guess what you maybe meant with "actual cities" was capitals/major cities. Bitcoin is everywhere - not only in New York City, London & Moscow. But if there's really is an obvious mistake in there, please let us know. Source for the markers was: http://coinmap.org/
